I'm having (I think) timing issues in relation to bridged T1-T1 calls via dynamic spans. Fax calls are intermittently working, but voice is fine. My box has a Sangoma A400 inside it as the primary Zaptel timing source. My T1 PRIs that are hooked to the box come in via a foneBRIDGE2 (dynamic TDMoE spans). PRI #1 is the telco and PRI #2 is an existing Comdial FX-II. For some reason, bridged TDM calls (when it comes to faxing) must be having timing issues since they intermittently fail.
I found what seems to be an issue in zaptel.conf (timing source for the Comdial side was 2 - changed to 0), but I don't know if that's it. I've also turned off echo cancellation. Any other thoughts on why I may be having what seem to be timing issues? Also, is timing passed through on dynamic spans & bridged calls? And is there a way to verify this?
