[cisco-voip] Extension Mobility and RCC

[Matthew Collins]

Hi Reto,

I came across this feature a few years ago back in CUCM V6 and MOC. This was a working feature of lync (Or MOC back then). As the Lycn can’t tell what device to control as there are two devices with the end users extension (fixed phone and EM profile). To get around this lync places a call to its self. The first phone to answer is then selected as the phone Lycn will use until the user signs out again.

Hello Group

we run a UCM / IM&P 9.1 and have RCC set up with Lync.
For a project office we introduced Extension Mobility. Some users now have their number shared on a fixed IP Phone in their office and use EM in the project office.
When the user is logged on with EM in the project office and they log on to Lync the IP Phone in the office dials its own number and plays the busy tone for 30 seconds.

Has anybody seen this behaviour or knows why the office phone dials itself?

Any help is appreciated.
Regards Reto
