Hello. <br>
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.<br>
<br>
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.<br>
<br>
IP PHONE -----> B1 (ISDN) chan capi AT * ----------> S0 BUS HIPATH ---------> PSTN<br>
<br>
Does anybody know any useful trick to solve this?<br>
I know that may be it is a signaling problem and isdn related question, but if someone can help me it would be great.<br>
<br>
Pardon my bad English and thanks.<br>
<br>
Some configured parameters:<br>
