Hi, I'm doing a GSM call bridge between two phones connected to a nanoBTS, with no dtmf. I am facing an issue only when setting ringback; here's my dialplan python code: bts_command="{ignore_early_media=true,bridge_early_media=false}sofia/gateway/gw/43112" session.answer() session.execute("set","ringback=local_stream://moh") -> plays the stream at 8000 Khz session.execute("bridge", bts_command) The problem is that when the B-peer answers, A-party ringback stops and I *can not* hear the B-party. If I'm doing this without the ringback line it works ok. See logs at [1] for this scenario. This is not happening with PCMA codec tests (which also have dtmf codec). I tried also libearal or disabled DTMF without success. I am using FreeSWITCH version: 1.6.12~64bit ( 64bit) Did something similar happen to someone before and has an idea how to fix this, while still keeping the ringback tone?
