Hi
If you configure PSTN-SiteB DN on PSTN phone as remote destination, enable MVA for the same number for Site B phone 1. If you dial in from PSTN phone with PSTN-SiteB DN to SiteB Phone 1 (via SiteB gateway) the call momentarily connects and fails (with isdn error code as unspecified resource unavailable). If have a transcoder configured locally on H323 SiteB gateway, then call will not fail. I have g711ulaw and g729 software MTPs configured on gateway for both scenarios. Seems strange to me. Can someone please explain why it happens?
Thanks,
Rahm
