ISDN+Asterisk+IVR Help:)


I have a problem whit my Asterisk. I have a ISDN Fritz!Card whit mISDN drivers. My infrastrukture looks that:

Analog Phone ----> Slican Pbx -----> Astersik

Between Slican Pbx and Asterisk is ISDN (DSS1) protocol. When i call a number Asterisk recived a Call and everythig is OK.

Now a try to build an IVR and i Write in extensions.conf:

exten => s,1,Answer()
exten => s,2,Background(vm-enter-num-to-call)
exten => 1,1,Goto(Tom,s,1)

exten => s,1,Dial(SIP/111,15|t)
exten => s,2,Hangup()

When i Call I hear Background(vm-enter-num-to-call), but when I put “1” I have TimeOut and Asterisk ends my Call. I think problem is whit interpretation DSS1 Asterisk.

Pleas help I have no more ideas
Sory for my ENG
