I installed UC520-7.1.3-ea version on my UC520 (8 users model) and configured SNR. It seems to work ok on a 7942 I used, but when I configured it on a 7921 I encountered a problem. The "Mobility" option in the soft key didn't seem to work (although it appeared and was clickable). This resulted in 2 things:
1) When you call the ext. it also rings the mobile (as expected) and you can pick the call on the mobile and can even transfer the call back to the IP phone. But when you click "Mobility" in order to send the call to the mobile device, nothing happens (you don't even get the messege: "send call to mobile device"). you click the "Mobility" and it just doesn't do anything (the calls continues normally on the IP phone and that's it).
2) When the phone is idle (not in a call) and you click the "Mobility" option in order to enable/disable Mobility, nothing happens (again, you don't even get the message "Enable/Disable Mobility").
These 2 work well when I tested on 7942 (didn't try any other phone type yet).
Any known issue with the 7921 and SNR feature on UC500?
