The problem is that Callproceeding does not always come from the remote it may be generated by the gatekeeper. MERA where sending fast start elements in the Call proceeding and connect. The call proceeding where not valid and causing the media to fail. Normally (although valid) EP's do not set Fast Start in Call proceeding so the code was disabled to resolve the MERA issue. if you wont read "bugs" file in mod_h323, there is explaned how to enable it.
