I dont want to start a RTFM thread, but can someone jsut clear this up for me. In zapata.conf I have ; ; Zapata telephony interface ; ; Configuration file [trunkgroups] [channels] language=en context=incoming signaling=v23 rxwink=300 ; Atlas seems to use long (250ms) winks usecallerid=yes hidecallerid=no callwaiting=yes usecallingpres=yes callwaitingcallerid=yes threewaycalling=yes transfer=yes cancallforward=yes callreturn=yes echocancel=yes echocancelwhenbridged=no echotraining=800 rxgain=0 txgain=0 group=0 callgroup=1 pickupgroup=1 immediate=yes musiconhold=default channel =>1 faxdetect=incoming ;Include AMP configs #include zapata_additional.conf ;Include genzaptelconf configs #include zapata-auto.conf The context=incoming part, does this mean on that line/channel that it is to use the [incoming] block I have in my extensions.conf file? Which is just [incoming] exten => s,1,Dial(SIP/200&SIP/201,20,tr) exten => s,2,Voicemail,u1000 exten => s,102,Voicemail,b1000 So what ever you set context= to has to have its own entry in the extension.conf file? Also I have faxdetect=incoming what context is this using in the extension.conf file? Thanks. faxdetect=incoming
