Hi All, Thanks for your time to look into this issue. I want to create 5 channels for outgoing and 25 channels for incoming. But i am unable to do so. Here is how my chan_dahadi.conf looks like [channels] language=en rxgain=1.0 txgain=1.0 usecallerid=yes callerid=asreceived busydetect=no context=default echotraining=no echocancel=yes echocancelwhenbridged=no usecallingpres=yes callprogress=no prilocaldialplan=unknown pridialplan=unknown overlapdial=yes switchtype=euroisdn immediate=no group=0 signalling=pri_cpe ;Digium T122P port 1 context=from-pstn (Incoming) channel => 1-15 channel => 17-26 context=outgoing (Outgoing) group=25 channel => 27-31 Here is how my extensions.conf looks like [outgoing] exten => _9.,1,Dial(DAHDI/g25/${EXTEN:1}) exten => _9.,1,Dial(DAHDI/28/${EXTEN:1}) However g25 doesnot picks up the channels between 27-31 and fails to execute, so i comment that line, and use dedicated channels to make call like the one here eg.channel 28 and calls go through perfectly Please advice, i think i am making some mistake somewhere. Your response will be highly appreciated. -------------- next part -------------- An HTML attachment was scrubbed...
