Hello freeswitch-users, I've encountered the following problem. Outgoing INVITE message from FS has no SDP in proxy_media mode. (in default mode(hard proxy?), everything is working fine.) test enviorment is the following: SIP client (CSipSample) ---> FS ---> other SIP server I've configured the following configuration at FS for proxy_media mode. [sip_profile] <param name="inbound-late-negotiation" value="true"/> [dialplan] <extension name="public_extensions"> <condition field="destination_number" expression="(.+)$"> <action application="set" data="proxy_media=true"/> <action application="export" data="codec_string=${ep_codec_string}"/> <action application="bridge" data="sofia/trunk/$1@yyy.yyy.yyy.yyy"/> </condition> </extension> [freeswitch version] ./freeswitch -version FreeSWITCH version: 1.5.1b+git~20130624T105435Z~275f2cf092 this is INVITE message from SIP client.
