Cannot recieve calls from Cisco VCS when signed in to Polycom Phone

Hi,

 

We have integration setup between our Cisco VCS environment and Lync 2013. I am able to call VCS endpoints from my Lync client and recieve calls from the VCS, however if I am logged into my VVX500, the incoming calls are regected straight away.

I believe this to be a codec negotiation issue, however cannot find any information on how I can resolve it. Is there any way to get the VVX 500 to ignore the incoming call from the VCS so it can be answered on the desktop?

 

Thanks

Hello Sach,

welcome to the Polycom Community.

It is always useful to include the currently used UC 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 regards to your issue you may miss understand how a SIP Invite works.

 

I suggest you check this post here:
