We have been having intermittent one-way audio recently with VZB wholesale SIP TNs. It may be limited to calling VZ retail SIP TNs Our RTP captures indicate RTP addresses we've never been told about by VZ. Has anyone else experienced this? Has anyone been notified by VZ that the RTP addresses of the VBZ servers have changed? This is at least the 2nd time we've seen this in the past year. Our VZB sales rep is *totally* useless.
