Has anyone ever programmed the IPO or an ASBCE to update the sdp with a re-invite notating that the PT=101? My customer has AT&T and intermittently inbound calls are having audio issues and AT&T stated we should try to Re-Invite the session with an update payload type 101. Never heard of this nor would I know how that is done. The IPO default PT is already set to 101 on the VOIP tab
