Hi list, I have an issue in my Freeswich in SBC mode. It's a call from Freeswitch to my endpoint, my endpoint answer G729, after this 200OK, my end-point re-invite in G711A, and my freeswitch say: "Codec G.729 decoder error". Ex : 1) SIP Provider ----INVITE(PCMA, G729)-----> FS ----INVITE(PCMA, G729)-----> End-point 2) SIP Provider <-----(200 OK G729)------ FS <------(200OK G729)------ End-point 3) FS <------(Re-INVITE PCMA)------ End-point 4) FS Error "Codec G.729 decoder error" in logs In fact, it's something like http://jira.freeswitch.org/browse/FS-3739, but the patch doesn't seem to work in our situation. My freeswitch's conf: *sip_profile TOTO: * * <!-- dtmf method -->* * <param name="dtmf-type" value="rfc2833"/>* * * * <!-- Payload type if the DTMF method is rfc2833 -->* * <param name="rfc2833-pt" value="101"/>* * * * <param name="inbound-late-negotiation" value="true"/>* * * * <param name="inbound-codec-prefs" value="PCMA,G729,PCMU"/>* * * * <param name="outbound-codec-prefs" value="PCMA,G729,PCMU"/>* *Diaplan TITI:* *<action application="export" data="codec_string=${ep_codec_string}"/>* *<action application="set" data="hangup_after_bridge=true"/>* * <action application="set" data="ignore_early_media=true"/>* *<action application="set" data="inherit_codec=true"/>* *<action application="export" data="t38_passthru=true"/>* *<action application="export" data="suppress_cng=true"/>* *<action application="bridge" data="* * {* * sip_invite_params=user=phone,* * sip_cid_type=none,* * ignore_display_updates=true,* * sip_renegotiate_codec_on_reinvite=true,* * }* * sofia/gateway/${distributor(LISTTMP ${sofia(profile TITIPRO gwlist down)})}/${numberdest}"/>* * * * * We choosed to use inbound-late-negotation with inherit-codec because of our t38_passthru option (as described here in FS wiki, I don't exactly remember where) To resolve this problem, we tried to find how to make FS forward the Re-INVITE received on B-Leg to the A-Leg, but we didn't found any solution... If someone have an idea, it would be great ! ;-) Thanks a lot, * Bien cordialement, Best Regards, **Kevin MATHY* * * --
