Hello all, I have a few questions regarding the t38-passthru sofia param. One of the ways we are using FreeSWITCH is as a simple B2BUA in our SBCs. The topology looks like this: Freeswitch /\ \/ FS and Asterisk boxen -> OpenSIPS -> PSTN The Freeswitch instance is setup with inbound late negotiation and bypass media = true and the dialplan consists of a very simple bridge statement that sends a call back to the proxy. The problem is that when someone sends a fax and the GW send a t.38 reINVITE, Freeswitch is sending the original SDP (PCMU in this case) back to Leg A and the fax then fails using PCMU. Is this parameter needed when bypass media is already enabled? Thanks, Spencer
