For the VVX500 (UC software 4.0.5), is there any method to assign a ring class to an incoming call based on a SIP invite header field other than Alert-Info? I am working with a call server that provides an auto-answer indicator in both the Call-Info and Answer-Mode fields, but does not include Alert-Info.
welcome to the Polycom Community.
To my knowledge we only support the Alert-Info field. Can your SIP server not be changed to utilize the Alert-Info field?
Call-Info is used for RFC 3265 SIP Specific Event Notification framework i.e.call appearance state notification.

I have made some inquiries about that as well.
We're dealing with one mixed environment where the Polycom phones are the 1/3 that lack a method to auto-answer the current group pages, so I thought it would make sense to look at both sides. One provides a per-line auto-answer setting so we can set up a dedicated intercom line, and the other has a built in rule to look for "answer-after=0" in the Call-Info field, in addition to the Alert-Info rules.
Thank you, and I will provide an update for whatever solution we find.
