[Asterisk-Users] Help to configure asterisk to dial to an PSTNline

Hello Tomek,
I suspect I may have located my problem.  The Hisax driver supports
NI-1, but I believe my CO is sending signalling in 5ESS, which does not
seem to be supported by the hisax driver....

Looks like it's back to the drawing board...

It depends on the hardware you have.
This is for an ISDN line.

This means that if you dial 01234567 on your sip phone (_0.), Asterisk
will dial Modem/group1 (which is configured in modem.conf), and dial
your extension (${EXTEN) 01234567, without the first number (:1})



exten => _0.,1,Dial(Modem/g1:${EXTEN:1}) ; can be also Modem/ttyI0; will
call through ; first available /dev/ttyI though exten =>
_0.,2,Congestion


Dialing 6712 on your sip phone will call 12.

exten => 6712,1,Dial(Modem/ttyI0:12)


Try reading Asterisk Handbook Project, it should be explained there for
your configuration I think.
