PSTN Callers on Conference Get 'Stuck' Muted RRS feed

  • Question

  • We are using the OCS 2007 R2 Conference Calling service to setup and manage conference calls where participants call in from a mix of PSTN and MOC and are seeing a consistently odd behavior for the PSTN participants.  If a PSTN participant is silent for several minutes (seems like ~5) and then speaks, it takes 5-10 seconds of them speaking before their audio is sent to other participants in the conference call.  Once their audio starts flowing there is no issue, but the behavior is very consistnet (and annoying for the folks calling from PSTN lines).  We do not see this issue for callers joining from MOC.

    PSTN connectivity is provided via a Quintim Tenor DX gateway with a single T1.
