Configuring Snom UC Edition for Lync

  • Article

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. 

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 to make announcements.

The following guide has been generalised to assist with configuring any snom UC device.

Once you have plugged in and powered up the device, browse to the web management portal. The default address is 192.168.0.2/16, otherwise if you have DHCP the device will get an address automatically. To get the IP Address form the PA1 push the IP/Reset button and it will read it out over the connected speakers. If you have a phone you can use the menu system to find it under "Information" - "IPAdr"

e.g. https://192.168.0.2

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 have just set:

If you haven’t already you will need to register and install the Snom UC edition software.

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.
