Hi, I have 2 port Digium PRI card (TE205P). On each port we have different service provider E1 is connected. I have to configure if i dial with prefix 910 it has to dial out through port 1 service provider and if i dial prefix 912 it has to dial out through port 2. My zapatel.conf: [trunkgroups] [channels] callgroup=0 pickupgroup=1 switchtype=euroisdn language=en signalling=pri_cpe usecallerid=yes callerid=asreceived callprogress=no busydetect=no context=from-pstn echocancel=no echocancelwhenbridged=yes resetinterval=never priindication=outofband group=0 channel => 1-15,17-31 group=1 channel => 32-46,48-62 vi extensions_additional.conf OUT_1 = ZAP/g0 OUTCID_1 OUTMAXCHANS_1 OUTFAIL_1 OUTPREFIX_1 OUTDISABLE_1 = off OUTKEEPCID_1 = off FORCEDOUTCID_1 OUT_3 = ZAP/g1 OUTCID_3 OUTMAXCHANS_3 OUTFAIL_3 OUTPREFIX_3 OUTDISABLE_3 = off OUTKEEPCID_3 = off FORCEDOUTCID_3 [outbound-allroutes] include => outrt-004-outbout include => outrt-005-newout exten => _!,1,Macro(user-callerid,SKIPTTL,) ; end of [outbound-allroutes] [outrt-004-outbout] include => outrt-004-outbout-custom exten => _912.,1,Macro(user-callerid,SKIPTTL,) exten => _912.,n,Set(_NODEST=) exten => _912.,n,Macro(record-enable,${AMPUSER},OUT,) exten => _912.,n,Macro(dialout-trunk,3,${EXTEN},,) exten => _912.,n,Macro(outisbusy,) ; end of [outrt-004-outbout] [outrt-005-newout] include => outrt-005-newout-custom exten => _910.,1,Macro(user-callerid,SKIPTTL,) exten => _910.,n,Set(_NODEST=) exten => _910.,n,Macro(record-enable,${AMPUSER},OUT,) exten => _910.,n,Macro(dialout-trunk,1,${EXTEN},,) exten => _910.,n,Macro(outisbusy,) ; end of [outrt-005-newout] But when i dial it gives error all circuits are busy. Is there anything i have missed. Thanks & Regards Chima.s
