Dear Support,
we have the problem that the Polycom CX5500 send only UDP request to our Lync Front End.
We have setup the Polycom and every setting that was possible to change to TCP we have changed.
000048.380|sip |4|00|Registration failed User: Username, Error Code:480 Temporarily not available
000057.655|copy |4|00|Configuration of URL failed
Thank you

The solution that the CX5500 comunicate via TCP is:
to setup the device to TCP Preferred
The option TCP only isn't work.

Hello UniAndre,
welcome to the Polycom Community.
It is always useful to include the currently used software version as issues experienced may already be addressed in a newer release.
This also allows yourself and others to check against current software release notes.
The above is also stated in the "Read First: Welcome to the Polycom VoIP Forum"
Therefore the Polycom VoIP FAQ contains this post here:
Question: How can I find out my SIP UC Software Version or the BootROM Version of my Phone?
Resolution: Please check here
In addition is this via SIngle Sign In or Pin & Extension ?

Hello UniAndre,
as mentioned already it is useful to provide the currently used software version as this may help identifying if this is a software problem.
I have not had any issues using the CX5500 signing into LYNC in my own or other customer setups having to change any parameters so this may simply be an issue in your network.
