Escene ES205 compact IP phone overview

The growth rate and, as a consequence, the increase in the cost of equipment significantly reduces the number of IP phone models that can be used in projects. On the other hand, companies are not ready to abandon the usual quality level of corporate phones.

In response to numerous requests from partners, Escene launches sales of new low-cost IP phones, with the most attractive price in the ES corporate lineup.

The compact office phone ES205, retains the quality features of the corporate line (cast tube, separate plastic round buttons, stand) for less money than the older models.
The phone is made in a strict and elegant style, made of high quality materials, has a large clear screen, two independent lines, an intuitive interface in Russian, a large set of functions, two Ethernet ports and power over PoE (optional), and also supports voice transmission in HD quality.
')
The device is presented in two models: Escene ES205-PN with PoE support (power supply via Ethernet) and Escene ES205-N (without PoE support — it is equipped with the Escence AD200 power supply unit). For a model with a PoE power supply unit is not included in the kit, but if necessary it can be purchased separately.

The delivery package for the Escene ES205-PN model is missing the Escence AD200 power supply unit (5 volts), it must be ordered separately.


Phone

Front panel and hardware buttons



The buttons on the phone are less than on older models, but this does not nearly interfere with its configuration and use. It seems that more buttons are not needed.

Conventionally, there are three blocks of buttons:

1. The multifunction buttons are four soft buttons under the phone screen, each of the multifunction buttons shows the function currently active, for example, “New call”, end a call, “Do not disturb”, “Call transfer” and others.

When navigating the menu, these buttons are also used for navigation, for example, “Back”, “Enter” and others, besides there are two navigation buttons “Up” and “Down” in the block and the multifunctional button for deleting the “C” symbol.

2. Line control buttons - the phone has two independent SIP accounts (two SIP lines). By default, outgoing calls are established from line 1, unless of course it is set up, if necessary to make a call from line 2, you need to press the line button, then dial the number — the phone will send the call through the second SIP account. The phone can accept two simultaneous calls. The “Line 1” and “Line 2” buttons are the light indication, when a call arrives, the diode of the line to which the call is being received flashes. If the line is busy, the line button is lit in red; if it is flashing, an incoming call has arrived. If the line is green, an active call is on the line; if it is flashing, the call is held on the line.

3. Service buttons - Redial redial button, two buttons for volume control and a speakerphone on button.

Back of phone



On the back of the phone is a standard sticker with the model number, serial number and MAC address. If, for convenience, you need to bring the handset wires or power cables to the top of the phone, you can put them on the phone body, for this, there are two grooves on the panel.


Installation stand

The phone stand is very easy to install - you need to align the lower guides of the stand with the slots in the phone case, then leaning on the lower guides to raise the stand counterclockwise until it clicks. As can be seen from the image, the stand can be fixed in two positions.

Phone Interfaces & Connectors



The first photo shows a block of interfaces. For AC power using the power adapter, there is a 5 volt socket on the panel, a connector for connecting a tube with an RJ9 socket. Two Ethernet interfaces - PC for connecting the phone to a computer and LAN for connecting to a local network and PoE power.
Below in the image is a view of the back panel with the wires connected, I did not begin to remove them. Wires do not interfere with the phone is exactly on the table and does not move during dialing, conversation and other actions.


Rear panel with connected wires

View of the phone on the table

So the phone looks assembled, high-quality plastic, the screen backlight is missing, but the contrast of the text and the screen is quite bright. When the phone first appears on the table, it feels how compact it is.



Phone screen

It is worth noting a nice screen with good resolution. The phone has a monochrome LCD screen without backlight size 128 * 64, small, but its size is enough to easily read the information from the screen.



This is how the phone screen with the registered line in Russian looks. “Line1” and “Line 2” is an arbitrary label that is configured in the “SIP Accounts” menu and is called “Label”.



Enter and dial numbers. When you enter a number, the numbers on the screen are large and readable. When you enter the first digits of the phone number, it shows the most similar numbers by the dialed mask. When dialing a number, the button of the line through which the number is dialed lights up in red.



Incoming call. In addition to the beep and on-screen indications, when an incoming call is in progress, the button of the line to which the call has arrived flashes.



State of conversation. During a call, the line button is green. There is a talk time timer on the screen.



Call logs.

Phone setup


The phone can be configured either using the on-screen menu or using the web-based interface. Unlike most phones from other manufacturers, which leave a minimum of settings in the phone menu and a larger number only through the web interface, the Escene developers decided to make available from the phone menu in addition to the standard settings, settings related to SIP accounts. That is, the phone can be fully customized using the on-screen menu.

Such a move is fully justified, in some cases, you can configure the phone faster. In addition, sometimes there may be problems with access to the phone through a web-interface or it may be necessary to explain to an employee remotely how to reconfigure his phone. It will be easier for an unprepared person to use the phone menu, rather than a web interface.

Initial setup using phone buttons

So, we turned on the phone, connected the LAN port to the local network that has access to the IP PBX. Employee's computer through the cable connected to the PC port.

Now we need to include the Russian language in the menu. Press the softkey "Menu", it is located on the left below the screen, a menu will open. Use the Up or Down navigation buttons to navigate the menu, press the corresponding button on the phone’s dialer or a soft button (for example, Enter) to select a menu item, use the Back button to return to the previous item.

Next, press the number 3, which corresponds to the choice of the “System Settings” menu, then select “Phone Setting” (number 3), then “Language” (number 1), using the Up or Down buttons to select “Russian” and Click "OK"
Then press the "C" button until you exit the menu.

Configure network settings:

Click "Menu", then select the "System Settings" menu (or press the number 3), number 2 - "Advanced Settings", the default password is empty, just click "OK". If you need to configure a VLAN (menu item 2 - “Network”, 3 - VLAN), go to the appropriate menu and configure its ID and priority. Next, select "Network", then "LAN port", by default, after loading the phone, a DHCP client is enabled, which is trying to obtain an IP address, therefore there must be a DHCP server on the network where the IP phone is located. If all settings are correct, the phone will receive an IP address and will be ready for further configuration.

If you need to use a static IP address, while in the “LAN port” menu, select “Static” and click “OK”. By default, the phone is configured with IP 192.168.0.149, to change the settings of the IP address, mask, gateway and DNS, use the menu buttons and navigation keys, after saving the settings, the phone will reboot. I pay attention that in this menu “LAN port” you can configure the port for access to the web-interface, by default it is 80, and also the port for access to the phone via telnet.

The PC port setting deserves special attention (Menu -> Settings -> Advanced Settings -> Network -> PC Port). Here you can configure the network operation mode between the PC and LAN ports. In bridge mode, this is a two-port switch with support for a separate tagged or untagged VLAN for a LAN or PC port. If you set the “Router” mode, the PC port is assigned an IP and a mask, the NAT address translation is enabled between the LAN and the PC, you can also enable the DHCP server. Thus, the phone becomes also a router with NAT support.

Now you need to check the correctness of the network settings and see the IP address that was assigned by DHCP, to do this, click "Menu", press the number 1 - "View status", use the Up or Down navigation buttons, find the IP assigned to the phone, in my case the IP address assigned by DHCP: 192.168.1.14

Setting up additional phone features

All these settings are made in the “Menu” -> “Functions” (number 2)


Support for additional services (DVO) and programmable buttons


The phone supports two independent SIP accounts, that is, registration on two different IP PBXs. At simultaneous registration of both lines, by default, the first line will be used. To switch to the second line (it should be configured) and return to the first one, use the “Line 1” and “Line 2” buttons.

I note that the phone supports two simultaneous calls, so to use simultaneous SIP registration on both lines in the SIP account settings for each line, you must set the "Number of lines used by the account" parameter to 1 (default value is 2). That is, the device supports only two lines, you can distribute them at your discretion: either assign both lines to the first SIP account, or distribute one line to each SIP account and register both at the same time.

As for the DVO, they all work correctly:


To access call logs:


Phone web interface


To access the web interface from a computer that has access to the network where the phone is located, enter the IP address of the phone in the address bar of the web browser, in my case it is 192.168.1.36.

Default login and password: root / root



We get to the main menu of the web configurator of the phone. For convenience of setting, we immediately select the Russian language in the bottom left menu.

The menu is divided into several groups:



The choice of the Russian language and the menu.

The state of the phone . For him there is a separate menu of the same name:



The menu refers to the service settings, allows you to get detailed information about the status of settings and statistics of the phone, such as time in operation, the status and health of the network connection, the status of the registration of SIP-lines, the firmware version and others.

Network settings



Menu "Network" -> "LAN port":



Basic Settings Tab

You can specify one of three connection methods: DHCP, static IP, or PPPoE.

Advanced Settings Tab

Also important setting is HTTP and Telnet ports. They should be made non-standard if the phone is on an untrusted network (for example, with an external IP address on the Internet).
Also here you can configure Paging - group notification.

Menu "Network" -> "PC port"

L2 switching is switched on by default between the LAN and PC ports of the telephone - the “Bridge” mode. The phone can switch to L3 routing mode — a NAT address translation will start on the LAN port, an IP address will need to be configured on the PC port, and if necessary, a DHCP server must be enabled in which to set the pool of IP addresses for clients.


PC port setup.


PC port in routing mode.

Menu "Network" -> "Advanced Settings"

VPN Settings tab


VPN configuration

If you need to connect your phone via a secure VPN channel, this can be done directly from the phone, without buying additional equipment (for example, a VPN router), the phone supports L2TP and OpenVPN (SSL VPN). This is a very useful feature for several reasons.

Firstly, if you have several phones that need to be delivered to a remote office, there is no need to buy a VPN hub at each remote location, you just need to configure the VPN client built into the phone. Further, through the tunnel to register his phone on the IP PBX in the central office.

Secondly, VPN improves security, more and more administrators are thinking about how to protect terminals that are on the Internet, two problems are becoming more acute: the danger of hacking the terminal and the difficulty of accessing telecoms operators to configure it, because often the terminal is behind NAT. Using a VPN client solves both of these problems, so this useful feature will become increasingly popular. In the example, using the VPN type L2TP, a connection to the vpn.ucexpert.ru server was created.

VLAN Settings Tab


VLAN configuration

In a corporate network, it is recommended to isolate the computer network traffic from the voice network traffic, this is most often implemented using two VLANs. The phone supports VLAN on both ports.

VoIP Settings
The phone allows you to manage a large number of SIP signaling settings and settings for RTP media traffic.

Menu "SIP accounts" -> "Account 1"

Tab "Basic"
In addition to the standard SIP account settings - User Name (UserID), Name (AuthID) and password, there is a “Label” field, it allows you to insert an arbitrary line description that will be displayed on the phone screen.


SIP account setup

In addition to the primary IP address of the SIP server, you can add an additional IP SIP server. In case of unsuccessful registration during the timeout, which by default is 32 seconds, the address of the additional SIP server will be used for registration. The setting “Number of lines used by the account” should be equal to 1 if you need to use both lines, because the second line must be assigned to the second account. If you leave the value equal to 2, then when applying the settings of the second line, the phone will display a message that there are not enough lines.

Calls tab


Additional SIP account settings

Here you can specify additional settings to overcome NAT, enable DNS SRV.

Security tab


Encryption Setting

The phone supports encryption of RTP and SIP signaling traffic using TLS protocol.

Calls tab


Basic phone settings - Calls

In this menu, global functions for the phone are configured.

If you set up the SIP settings here, they will be applied to both lines automatically, except for the settings “Local SIP port” and “RTP port range”, which can be useful for properly configuring the firewall.

In case the call transfer is required to be performed with a special key combination (old code), instead of the standard SIP message 302, this can be specified in the setting “Special code for call transfer”. A useful setting that allows you not to break the connection in the conference, if it left the initiator. You can set call forwarding by condition (busy and “no answer”) and unconditional.

Here you can also set codes that will be transmitted when you press the “Pickup” buttons (the value in the “Call Pickup Code” field) and “Voice Mail” (the value in the “Voice Mail Number” field).

Intercept the call in three ways:


The important setting is “Return Code on Failure” and “Return Code at DND”, by default IP PBX returns SIP message 603 Decline, these messages can be changed to others, if necessary for correct interpretation of the reason for the release.

Tab "Forwarding VOIP calls"


Call Forwarding

The tab is set forwarding: unconditional, if the subscriber did not answer or the line is busy.

Internal phone book

The phone has a built-in phone book, which is quite advanced. It allows you to store up to 300 contact entries, each of which can store up to 3 phone numbers. Entries can be made via the phone's on-screen menu using the web-based interface. To download or save an already-created phone book in XML format, use the Phone Service menu -> Update over HTTP -> XML Phone Book; here you can save or load the phone book in XML format.


LDAP Corporate Book Setup

If your company uses an LDAP server, you can connect a phone to it and synchronize corporate contacts. 2 and 3 protocol versions are supported, as well as using the “LDAP Lookup For Incoming Call” and “LDAP Lookup For PreDial / Dial” settings, you can search for the contact name for an incoming and outgoing call. If the contact is in the LDAP directory, then its name will be automatically added to the number.

The phone also supports blacklists or ban lists: an unwanted phone number is added to such a list and can no longer reach you.

Service Settings


Menu "Phone Settings" -> "Basic"


Update and backup your phone

You can copy configuration files using three different protocols. FTP, TFTP and HTTP - the choice of a particular protocol is a matter of taste and convenience. Software update is extremely simple, you need to select the firmware file, then click update. If the version of the downloaded firmware of the phone is lower than the installed one, a window will appear with the inscription “Filename is illegal”. In the menu, you can also restart the phone or reset it to the factory settings.

Menu "Phone Settings" -> "Advanced Settings"


Debugging

To debug the phone, you can enable logging by specifying the necessary logs. You can view them in two ways:


Also, the phone has the ability to collect network dumps of packages into pcap files, which can then be analyzed using a sniffer, for example, Wireshark, this is an extremely effective debugging tool.

To start capturing packets, click the “Start” button. When finished, click the “Finish” button. To download the received dump, click the "Create backup" button. Also on the “Automatic Update” tab, you can configure the phone's firmware update according to the TFTP / FTP / HTTP / HTTPS protocols.

Security menu

Here you can set a username and password for the administrator and user of the phone, as well as download an SSL certificate.

Setting up connection to IP PBX Asterisk using web-interface

Suppose we need to configure two extensions (two SIP accounts). For example, the first entry on the IP PBX Asterisk, the second on the virtual IP PBX:

IP    Asterisk= 10.10.10.1 UserID=10 password= QOXZuTcZ38qlBsr SIP (Asterisk)= 10.10.10.1

In the Asterisk sip.conf configuration, this will be equivalent to:

 [10] deny=0.0.0.0/0.0.0.0 secret= QOXZuTcZ38qlBsr dtmfmode=rfc2833 canreinvite=no context=from-internal host=dynamic type=friend nat=yes port=5060 qualify=yes callgroup=01 pickupgroup=01 allow=g722 dial=SIP/10 mailbox=10@device permit=0.0.0.0/0.0.0.0 callerid=device <10> callcounter=yes faxdetect=no

Equivalently, when configured in the Free-PBX web interface, using the first line as an example:


FreePBX Setup


Setting up a SIP account for FreePBX

To work with Asterisk, just configure the Username (Username) = 10, password (Password) = QOXZuTcZ38qlBsr and SIP Server (SIP Server) = 10.10.10.1. You can add a label (Label) that will be displayed on the screen of the phone, in this case "L1 # 10".

You can reduce the re-registration time from standard 3600 seconds to 600 seconds, this is especially true if the IP PBX is located outside the office, for example, Virtual PBX. If the phone is on a local network and the IP PBX is on the Internet, no special settings are usually required to overcome NAT. Next, click the "Apply" button.

Exactly the same thing needs to be done with the second line, for example, city number 78126470011 on the SIP server West Coll. Let's register it on a virtual PBX with a non-standard SIP port 9966:

 userid=78126470011 authid=6470011 password= eIoMzKsf sip =uc.westcall.net port=9966


SIP account setup for virtual PBX

To specify a non-standard SIP port (other than 5060), you must explicitly specify it in the SIP server line: uc.westcall.net:9966. Next, click the "Apply" button.

In case of successful registration, the corresponding display will appear on the phone screen, so information on the status of line registration is available on the Status menu page:

Account 1: Registered
Account 2: Registered

In order to use the DVO buttons (transfer, hold, conference) no additional configuration is required.
