I’m using the confbridge application to synchronize announcement aims. At the begin of an announcement, a gong soundfile is playing using the playback application.
Every connections are a SIP connection using the G722 codec.
I start an announcement from a SIP phone and it will be called two announcement aims via SIP. If the two SIP connections are established. The gong soundfile is playing.
If the soundfile is playing I hear a loud crack on one of the two loudspeaker. I think it is a transcoding problem.
I have used several configuration of the confbridge.
If I’m using the option
in the bridge profile. I hear the crack after 2,5 seconds in every announcement.
If I’m using other internal_sample_rate setting. it works better but I hear a crack in one of three attemps.
I have try other settings in the confbride configuration but nothing solve the problem.
I’m using asterisk 13.1 and the old SIP channel (chan_sip).
Any idea to solve the problem?
