Hello, I have developed an endpoint which I call X1. Its objective is sending audio to / receiving audio from an external system. I originate a call, bridging extension 7550 with X1: bgapi originate {origination_caller_id_number=00000002}sofia/external/7550@192.168.1.200 <mailto:%7borigination_caller_id_number=00000002%7dsofia/external/7550@192.1 68.1.200> &bridge(X1/00000002) Extension 7550 is ringing and I answer it.

Here the audio sent to FreeSwitch is perfectly reproduced at the ext. 7550, while one received is more or less broken (there are many missing frames). I try to execute: switch_channel_t *channel = switch_core_session_get_channel(session); switch_channel_answer(channel); ... but it has no effect at all. Exactly after 60s FreeSwitch hangs up. 91407aa0-792a-4f10-bc4e-40d143dfc2e2 2017-11-27 14:45:42.000933 [NOTICE] switch_ivr_originate.c:3605 Hangup X1/83688055 [CS_CONSUME_MEDIA] [NO_ANSWER] What do I do wrong? May be I should originate a call to the extension 7550, then originate a call to my endpoint X1 and then bridge both? I'll appreciate very much any hint. Adrian.
