Hi all, till now I'm been working with pre-made setup files for FS, and now I'm trying to get a deep knowleadge of how the dialplan works. So I modifed my autoload_configs/sofia.conf.xml file and changed my dialplan param to something like this: <param name="dialplan" value="XML:/etc/freeswitch/ dialplans/t38_transcode.xml,inline:socket:127.0.0.1:8022 async full"/> The Idea is that it loads another .xml file especific task and also use a dialplan throught a socket to a daemon that handle the rest. On my t38_transcode.xml file ... very simple: <extension name="t38_transcode"> <condition field="sip_h_X-T38-Transcode" expresion="^True"/> <condition field="destination_number" expresion="^(\+1|1)?([2-9]\d\ d[2-9]\d{6})$"> <action application="set" data="fax_enable_t38=true"/> <action application="set" data="t38_trace=true"/> <action application="set" data="sip_execute_on_image=t38_gateway peer nocng"/> <action application="bridge" data="sofia/external/$1$2@proxy.server.tld"/> </condition> </extension> But If I fire a call to FS like [number]@[FS_IP] from a sip testing client I get [INFO] switch_core_state_machine.c:311 No Route, Aborting What I'm doing wrong here? My target its just I want to ANY call that came in with a SIP header of X-T39-Transcode=True (market by a sip proxy elsewhere on the net) just do a T38->Ulaw transcoding saving the T38 trace, so I could inspect it later. The rest of calls coming in ... as they don't have the sip-header should end on other app. For doing the testing I disabled the socket_inline part of the dialplan string, so it have only this: <param name="dialplan" value="XML:/etc/freeswitch/dialplans/t38_transcode.xml"/> Did I miss something? ... or maybe missundestood who the xml dialplan works ?
