Configuring Snom UC Edition for Lync

I have had a lot of success with the snom UC Edition software for snom phones. Currently the snom 300, snom 370, snom 710, snom 720, snom 760 and snom 821 are officially qualified for Lync 2013. The snom UC600 is a traditional IP desk phone especially designed for use with Microsoft Lync.

It is still possible to install the UC edition software on phones that are not officially qualified, the most recent for me being a snom PA1. Obviously there are no guarantees that all functionality will work, but so far I haven’t had any issues. The snom PA1 is a PA switch which picks up incoming calls automatically and outputs the audio to the built in 4 Watt amplifier, or to a line out connector if you want to connect it to a building PA system. In my case I have configured it as a Lync endpoint and connected to the speaker system throughout the building. Calling the configured Lync user enables staff make announcements.

The following guide has been generalised to assist with configuring any snom UC device. If you have not already installed UC edition then you will need to visit the Snom website and register, then copy the URL to the download file:

 

Once you have logged in to the phones web interface discussed below, navigate to “Software Update” – “Manual Software Update”, then paste the URL in and select “Load”. The phone will reboot and install the UC firmware.

Snom has a user mode and admin mode. When logged in in user mode you won’t see any of the advanced options. To access the advance options select “Setup”-“Advanced”, enter the default admin password “0000” then “Apply”:

There is no username and password out of the box. To set the
admin password and the HTTP web interface password navigate to “Setup”-“Advanced”-“QoS/Security”:

Select “Apply” then log back on using the HTTP server credentials you just set. Note that in some cases you may need to select “Save” at the top of the settings page:

Click on any identity from the left navigation panel of the snom
web interface:

Identity active: ON
Display Name: Name to display on phone where applicable
Account: SIP sign-in address NOT including @sipdomain.com e.g. peter.pan
Password: your lync password
Registrar: SIP domain e.g. neverland.co.nz
Authentication Name: Username e.g. [email protected] or NEVERLANDPeter.Pan

Note: If no Authentication Name is provided, the Account setting is used in place of the Authentication Name

Outbound Proxy: SIP server e.g. front end pool or access edge (lyncpool.domain.com/sip.domain.com)

Note: It is also possible to specify the port and transport layer: sip.domain.com:5060;transport=tcp  (Use
TCP/Port 5060) sip.domain.com:5061;transport=tls (Use TLS/Port 5061)

Note: Leaving out the Outbound Proxy will result in automatic DNS lookup for Lync (Auto Device Sign-in)

Ensure that “Server Type Support” is set to OCS/UC:

RTP Encryption should be set on “ON”:

Check that the user account has logged in successfully:

If you have any issues check out the SIP Trace and Log, unlike a lot of products these logs are very useful in finding the problem.
