Hi, I have problems while trying to dial from simple analog phone that attached to my TDM400P card. No matter which number i press i immediately get a congestion tone. when calling from outside (e.g cellphone )to the line on port 4 and pressing extension #123 everything works fine and i manage to make a connection. I've plugged on port(Zap) 4 the analog line and on port 1 the phone. port 4 - FXO module port 1 - FXS module my simple conf: *_zapata.conf:_* [channels] relaxdtmf=yes usecallerid=yes hidecallerid=no callwaiting=no threewaycalling=yes transfer=yes echocancel=yes echotraining=yes immediate=no ;define channels context=internal signalling=fxo_ks channel => 1 context=incoming signalling=fxs_ks channel => 4 _*zaptel.conf:*_ fxoks=1 fxsks=4 loadzone=il defaultzone=il _*extensions.conf:*_ [globals] DAVID=Zap/1 OUTBOUNDTRUNK=Zap/4 [incoming] exten => s,1,Answer() exten => s,2,Background(vm-enter-num-to-call) exten => 123,1,Dial(${DAVID},10) exten => 123,2,Playback(vm-nobodyavail) exten => 123,3,Hangup() exten => 123,102,Playback(tt-allbusy) exten => 123,103,Hangup() ;exten => 1,1,Playback(digits/1) # repeat vocaly the digit that pressed exten => i,1,Playback(pbx-invalid) exten => i,2,Goto(incoming,s,1) exten => t,1,Playback(vm-goodbye) exten => t,2,Hangup() [intrnal] include => outbound-local exten => 123,1,Dail(${DAVID},10) [outbound-local] gnorepat => 9 exten => _9X.,1,Dial(${OUTBOUNDTRUNK}/${EXTEN:1}) exten => _9X.,2,Congestion() exten => _9X.,123,Congestion() Thanks David
