In the persuit of deploying the most inexpensive Unified Comms deployment I have experienced an increasing interest in the SNOM 300 phone flashed with OCS firmware.
You would need to apply for access to the firmware to snom, which usually takes a day or two:
Whilst I personally prefer some of the more purposefully lync optimised devices, the price entry point on these devices do pose a viable option for certain deployments.
I managed to recover a variety of these units from a storeroom and found them running the version 6.5.2 firmware.
Important to note, if you snom 300 is on version 7.x firmware, you can update directly to the OCS compatible firmware. A factory reset is still required.
After a little digging, I managed to place the required firmware files in a http location. The firmware is then updated from the web interface on the device, in the following sequence:
1. Reset the phone to factory settings ( admin pwd “0000” – 4 zeros )
2. Navigate to the http/s interface on the phone via a web browser.
From there, sign into the phone and login via the “OCS ACCOUNT DATA” option on the menu and whola! You now have an inexpensive Lync (OCS Certified… ) endpoint!
