I hope that this email finds you all well. I have a problem with a Single Number Reach functionality. When I use Cisco UC540 or 560 with 15x IOS versions I noticed a problem with SNR. When I enable the feature and place a call to internal number, after the configured 10 secs, the call is redirected to my mobile phone, my mobile phone rings, but when I try to pickup the call on my mobile phone .. the call interrupt, but the internal number continues to ring.
First I thought that I have a problem with the codecs, but I made the test with UC520 with 12x IOs version...and the problem doesn't represent. I use a SIP trunk with our telco provider.
Marcos, I hope that you have an opinion
OK, thats a problem. Probably need to run traces and so forth and I would bet its external to UC500 (signaling or media issue to Mobile),
Best to open a case.
