Hi guys, I've a strange issue with FS , version svn -r10584 , when FS bridges a call first 3 seconds of audio are missing , looks that only happens on PSTN calls and using ringback or transfer_ringback. This only happens in calls from PSTN , not from VOIP. Some scenarios i tried to isolate this issue : - Issue PSTN --> FS ( brigde ) ringback/transfer_ringback -> PSTN - Good setting bypass_media before run bridge but i need rtp in FS path PSTN --> FS ( brigde ) ringback/transfer_ringback -> PSTN - Good PSTN --> FS ( brigde ) WITHOUT ringback/transfer_ringback -> PSTN - Always good VOIP --> FS ( brigde ) -> PSTN Dialplan has nothing wrong ( i guess ): <extension name="Transfers"> <condition field="destination_number" expression="^1??XXXXXXXXXX$"> <action application="answer"/> <action application="speak" data="cepstral|Allison-8kHz|blah"/> <action application="set" data="hangup_after_bridge=false"/> <action application="set" data="playback_terminators=#"/> <action application="set" data="ringback=$${us-ring}"/> <action application="set" data="transfer_ringback= $${hold_music}"/> <action application="set" data="effective_caller_id_name= ${caller_id_name}"/> <action application="set" data="effective_caller_id_number= ${caller_id_number}"/> <action application="set" data="originate_timeout=30"/> <action application="set" data="call_timeout=30"/> <action application="bridge" data="sofia/default/18008226235@PSTN_GW"/> <action application="speak" data="cepstral|Allison-8kHz|Transfer finished"/> <action application="hangup"/> </condition> </extension> Any ideas ?
