In the fall, we talked about a whole series of Snom M-series devices for creating DECT networks. A large M700 station was also described there, but such devices are redundant for small offices / shops / cafes and other small businesses. But in this niche the station Snom M300 perfectly settled, left overboard of that article, and quite fresh new Snom M200.

Snom m300

Since the Snom M300 is the “younger brother” of the M700, it is logical to compare some of their parameters.

So, the M300 is designed to create a DECT network in a relatively small area. As well as the 700th model, the “three hundred” has a maximum radius of action up to 50 m indoors and up to 300 m in open space. But it is in ideal conditions, in practice, the range depends on the materials and the thickness of the walls and floors.

At the same time, the M300 can operate up to 20 DECT snom M25, M65 and M85 tubes (M700 - up to 30 of any). At the same time, the supported SIP accounts are also 20. At the same time, the M300 cannot be combined into multi-cell networks, and this is an important difference from the older model. If the M700 can be connected to each other in dozens and hundreds, creating coverage in very large areas and serving a total of up to 1000 handsets, then the M300 is a “lone hero”. However, you can expand the coverage area of ​​this station with the help of M5 repeaters , which you can connect up to three pieces. At the same time, the M300 can handle up to 5 calls (the M700 can handle up to 5 broadband or up to 10 standard. The M300 also supports broadband).



To connect to an Ethernet network, the M300 is equipped with an RJ45 port. Not forgotten and the hardware reset button.

Setup and update are performed over the network via the web interface. Its built-in subscriber book in the M300 is not (in the M700 - 200 subscribers).

The station supports all necessary protocols:

• SIP (RFC3261)
• DHCP, NTP
• HTTP / HTTPS / TFTP
• Ldap

The list of supported codecs is even larger than that of the M700:

• G711 A-law, µlaw
• G722 (broadband)
• G726
• G729 (A / AB including VAD)

Security in the M300 is provided with support for wireless DECT encryption, TLS, SRTP protocols (RFC3711), SIPS and password protection of the web-based station management interface. Snom M300 is compatible with all major IP PBX systems, including those based on Broadsoft and Asterisk.

The station is powered by a 5 V power supply, its overall dimensions are 178 x 120 x 30 mm.



This station can also be purchased in the M325 package, which, besides the M300 itself, includes the DECT-phone Snom M25. About him in detail in one of the past publications on the devices of the M series.

Snom m215

This kit consists of a Snom M200SC base station and an M15SC DETC tube.



M200 in its capabilities more modest M300. Up to 6 DECT handsets can be connected to it at the same time, it supports the same number of SIP accounts. The station can handle up to 4 simultaneous conversations.

The range of the M200SC standard, up to 50 m in ideal conditions. It can be powered both from the power supply and via PoE.



On the front panel there is a button to search for a DECT handset: when you click on it, the phone starts ringing.


At the back is an RJ45 connector for connecting to a 10/100 BASE-T network.


The M200SC has a built-in phone book with 200 numbers, the same number of entries in the call log. The device is configured completely over the network, through a password-protected web interface. The station supports wireless firmware upgrade, has the functions of internal communication (within the local network) and three-way conference calling. Able to forward and hold calls.

The M200SC is compatible with GAP devices and the Asterisk platform. The sound quality of the M200 is not worse than that of the more advanced M300, supported audio codecs:

• G.711 a-law, u-law
• G.722
• G.726
• G.729
• ILBC

List of supported communication protocols:

• SIP (RFC3261)
• HTTP / HTTPS / TFTP / FTP
• DHCP, NTP, SNTP, STUN, VLAN
• RTP / SRTP
• IPv4 / IPv6
• Ldap

Security is not “compromised”: the M200SC supports a whole array of security tools, including TLS protocol, AES encryption, LLDP-MED, 802.1x and 802.1pq.

The included M215 handset, the M15SC, was one of the simplest in the Snom range. This is a reliable "workhorse", suitable for any organization, and even for use at home.


The phone is equipped with a display with a diagonal of 1.7 inches and a resolution of 90 x 65 pixels. The top line is usually used to place information icons, while the bottom line is used to indicate the values ​​of two function keys located directly below the display.


The keyboard is equipped with a backlight, the phone is also equipped with an LED that lights up when you receive voice mail. The phone supports call forwarding and call hold, allows you to assign 10 numbers for speed dialing.



Behind there is a removable clip for hanging the phone on the belt. On the right side there is a 2.5 mm headphone jack with a rubber plug.



The battery is nickel-metal hydride, with a capacity of 550 mA * h. This may be enough for a week of work in the standby mode and up to 7 hours of conversation.







The overall dimensions of the phone are 174 x 49 x 31 mm.
