Hello, could you please advise what SIP INFO is used in Polycom devices for updating display information within the already established SIP connection?
We are using device SoundStructure SW version 1.7.4 with card Policom VoIP: 3111-33215-001 Rev=2 Region=1.
We trying scenario attendant transfer and use Polycom as transfer target but it doesn’t update a display information.
Is it supporting on SoundStructure?
If yes, what SIP Info is using for such update?
