Hello Another rtpengine related question after having successfully implemented a dispatcher configuration. Call flow is ok, everything works well until I tried to increase call volume. Kamailio log showing "proxy replied with error: Ran out of ports" In the beginning both channels are up, then I can see a teardown on the incoming channel loosing the ability to collect DTMF. Using the CLI tool I have statistics showing that none (!) of the calls are "regular terminated", they are on timeout. After experimenting with handling BYE, I ended up could getting a "regular terminated" call by using route[RELAY] .... if (is_method("BYE")) {     rtpengine_delete(); } and then I can see some good things! Received command 'delete' from 127.0.0.1:58538 Scheduling deletion of call branch 'as65b95845' (via-branch '') in 5 seconds Replying to 'delete' from 127.0.0.1:58538 (elapsed time 0.000216 sec) Please correct me if I'm doing wrong this way! cheers Istvan
