SIP INFO Caller ID update


SIP INFO Caller ID update




Apparently, SNOM and Aastra phones support Caller ID updates during an established call based on SIP INFO messages :


Do Polycom phones support it too ?


Is there another way to update the caller ID of an established call ?

Re: SIP INFO Caller ID update

Hello Damien,


as you have not provided the exact RFC that includes this functionality I am unable to confirm if we officially support this feature.


I am aware that in SIP 3.2.6, UCS 3.3.2 and UCS 4.0.0 we added:


67622 Phone displays correct caller ID from a group pickup number


Above added the functionality on a re-INVITE to update the remote address or to allow to change the display if there is no "Remote-Party-ID" like header.


Best Regards
