can you add more debug to the following places (with your patch disabled)
ozmod_ss7_boost.c:245
zap_log(ZAP_LOG_CRIT, "setting init state to progress_media\n");
zap_io.c:999
zap_log(ZAP_LOG_CRIT, "init_state=%d\n", zchan->init_state);
mod_openzap.c:368
zap_log(ZAP_LOG_CRIT, "calling zap_channel_init\n");
also look for any purple veto lines during the call.
