[Asterisk-Users] asterisk and siemens hipath 3500

[Ricardo]

Hello.
I have asterisk with an old avm b1 v3.0 configured and working with capi
channel . The isdn card is connected to an S0 isdn bus of a  siemens hipath
3000  version 4.0 It is possible to make outgoing calls and receive too, but
I think that there is some kind of signaling problem when i call from an ip
phone or soft ip phone because i do not get ring or busy tone calling to any
PBX phone, but if i get outside line (i.e. calling a cell phone at PSTN)
then i can hear the busy or ring tones.

So, if i call to any pbx phone i do not hear anything until someone picks up
the phone and if it is busy i do not know and after a while i get the normal
call clearing and the call is finished.

IP PHONE ----->  B1 (ISDN) chan capi AT * ----------> S0 BUS HIPATH
---------> PSTN

Does anybody know any useful trick to solve this?
I know that may be it is a signaling problem and isdn related question, but
if someone can help me it would be great.

Pardon my bad English and thanks.
