CISCO 7942G and 7940 phones in conjunction with Asterisk 11
These devices fell into my hands. I am not on friendly terms with Cisco because I got into Google and set up these devices. This article helped a lot , but there are errors in it that are not compatible with some revisions of the 7942G.
Out of the box, the phones work with Tsis protocols, so you must first flash on SIP.
Let's start from scratch.
DHCP in my case is MikroTik. Add in the properties of the DHCP server 150 an option with the value '10 .1.1.1', where 10.1.1.1 is your future TFTP server. We register it with single quotes. In some cases, it is said to specify the 66 as an option, but it did not work for me.
')
I did everything on the same CentOS 6.7. It's simple. tftp-server is in the starting delivery, so you don’t need to install it. If anything:
Turn it on and let him write logs.
In this file, we are interested in the server_args and disable lines. First we bring to the form:
The second is just put no .
Create a folder and give rights:
Reboot and enjoy:
I collected the file - settings, firmware and Russian locale. Just unzip to root / tftpboot. You can download it here .
Immediately configure the phone. In the SEPmymac.cnf.xml file, change the SIP_NUM to the user number on the asterisk, SIP_PASS, respectively, the password. Instead of 10.1.1.99 we specify our telephony server. The file itself is renamed - mymac is changed to the device poppy in capital letters.
In line:
Specify the time zone. In tsisok all his own, even time zones. The time zone of Kaliningrad sought a half day In the end, here:
A couple of lines below indicate the NTP server. For this purpose, I raised it to the very same CentOS, where Asterisk is spinning.
To begin, install, if not worth it:
The config lies in /etc/ntp.conf. We add there a line where we specify the subnet that has access to this server.
We start the server:
When enabled, Cisco 7942 will now attempt to pull up the config from the TFTP server. The config also contains the firmware, it will also pull it up. In total, it should be loaded with the necessary firmware, settings and locale. It will take time, but the whole process will be displayed on the screen.
For normal operation of the 7942G, a dialplan.xml file is also required, which must also lie in the root of the TFTP server. Paste the following content into it.
This machine came to me already flashed, but the logic is about the same. The config looks like this:
Uncomment the image line and specify the firmware version. Themselves take the firmware on the official website or on torrents. The config file is called SIPmymac.cnf - instead of mymac, again, the MAC address of the device.
We finish the calls.

Raise TFTP
I did everything on the same CentOS 6.7. It's simple. tftp-server is in the starting delivery, so you don’t need to install it. If anything:
yum install tftp-server Turn it on and let him write logs.
nano /etc/xinetd.d/tftp In this file, we are interested in the server_args and disable lines. First we bring to the form:
-p -c -u root -s /tftpboot -v
The second is just put no .
Create a folder and give rights:
mkdir /tftpboot && chmod 777 /tftpboot Reboot and enjoy:
service xinetd restart 7942G Firmware and Setup

A couple of lines below indicate the NTP server. For this purpose, I raised it to the very same CentOS, where Asterisk is spinning.
NTP server
To begin, install, if not worth it:
yum install ntp The config lies in /etc/ntp.conf. We add there a line where we specify the subnet that has access to this server.
restrict 10.0.0.0 mask 255.0.0.0 nomodify notrap
We start the server:
/etc/init.d/ntpd start Directly firmware
When enabled, Cisco 7942 will now attempt to pull up the config from the TFTP server. The config also contains the firmware, it will also pull it up. In total, it should be loaded with the necessary firmware, settings and locale. It will take time, but the whole process will be displayed on the screen.
For normal operation of the 7942G, a dialplan.xml file is also required, which must also lie in the root of the TFTP server. Paste the following content into it.
<DIALTEMPLATE> <TEMPLATE MATCH="*" Timeout="3"/> <!-- Anything else --> </DIALTEMPLATE> 7940
This machine came to me already flashed, but the logic is about the same. The config looks like this:
# SIP Default Configuration File # Image Version # image_version: P0S3-8-12-00 # Proxy Server proxy1_address: "10.1.1.99" proxy2_address: ""; proxy3_address: ""; proxy4_address: ""; proxy5_address: ""; proxy6_address: ""; # Proxy Server Port (default - 5060) proxy1_port: 5060 proxy2_port: 5060 proxy3_port: 5060 proxy4_port: 5060 proxy5_port: 5060 proxy6_port: 5060 # Proxy Registration (0-disable (default), 1-enable) proxy_register: 1 # Phone Registration Expiration [1-3932100 sec] (Default - 3600) timer_register_expires: 600 # Codec for media stream (g711ulaw (default), g711alaw, g729a) preferred_codec: g711alaw # NAT/Firewall Traversal nat_enable: 0; 0-Disabled (default), 1-Enabled nat_address: ""; WAN IP address of NAT box (dotted IP or DNS A record only) voip_control_port: 5060; UDP port used for SIP messages (default - 5060) start_media_port: 16384; Start RTP range for media (default - 16384) end_media_port: 32766; End RTP range for media (default - 32766) nat_received_processing: 0; 0-Disabled (default), 1-Enabled # SIP Configuration File # 7940 w/2 lines # Line 1 Parameters line1_name: "SIP_NUM" line1_shortname: "SIP_NUM" line1_authname: "SIP_NUM" line1_contact: "SIP_NUM" line1_displayname: "FirstName LastName" line1_password: "SIP_PASS" # Line 2 Parameters line2_name: "" line2_authname: "" line2_displayname: "" line2_password: "" # Phone Label (Text desired to be displayed in upper right corner) # Has no effect on SIP messaging phone_label: "" # Remote Access Parameters for console or telnet login phone_prompt: "SIP Phone" phone_password: "cisco" user_info: none Uncomment the image line and specify the firmware version. Themselves take the firmware on the official website or on torrents. The config file is called SIPmymac.cnf - instead of mymac, again, the MAC address of the device.
