This read-write TruthValue controls whether the module accepts more than one SSRC (Synchronization Source) per RTP session, with true allowing multiple SSRCs and false restricting each session to a single SSRC. An admin cares because some RTP sources or transcoding scenarios legitimately switch SSRC mid-session, and rejecting that can cause audio dropouts if this is set to false. For example, an operator integrating with an endpoint known to change SSRC during a call (such as after a failover) would set this to true to avoid the module discarding the resumed stream.
