Description (partial)

Symptom:

In Telepresence B2B testing through Cube, ASA and SBC, seeing an issue with following scenarios-
1. B2B Point to Point Call after call is setup signaling and media wise, one endpoint is put on Hold and an immediate Resume results in no media flowing.
2.B2B Point to Point Call between two endpoints A1 in Ent A and B1 in Ent B. after call is setup signaling and media wise, an Audio-addin joins the Conf call setup at B1, after hitting Conference, no video is seen.


Conditions:

The problem is when second invite was got, the ASA thinks that it has pinholes but before RTP could go through, the pinholes timed out. In scenario 1 after a Hold if we wait for anything between 15sec to 3 minutes, the pinholes opened from first Invite were all removed before the second invite was sent and new set of pinholes were opened and RTP could go through.  
Scenario 2  Need to wait for 15sec -3 minutes after the Audio addin call is answered at B1 before it can be conferenced into the existing Conference call between A1 -B1.
