Hi

I'm experimenting with asterisk IP PBX. I have plugged in an old ISDN
modem card, and used it to interconnect through an S0 channel with an
existing ISDN line. That worked (in both directions).

Now I wanted to interconnect with our existing PBX (telrad digital key IS 128) through
one of it's S0 channels (client site, don't know if that makes a
difference).

I can dial from the existing PBX to an asterisk extention,
communication works fine. But if I try the oposite, dialing from
asterisk to existing PBX, the phone rings (the phone on the telrad
pbx), the user picks his phone up but asterisks doesn't see that,
instead I get a busy message in asterisk. (
Dialing out from asterisk through telrax PBX to external numbers (via PRI line) works
fine

anybody an idea? Can I view logs somewhere? Somebody gave me a tip about bearer type, but that didn't bring me any closer

thx in advance
Arne

Arne,
Tell me again what you're trying to do? Are you setting up a connection via an ETSI BRS port? Explain the kit at each end of the link and what you are trying to achieve. Andy

Did you have any luck, I am trying to get asterisk working with telrad 128KSU via T1 and am having issues getting the telrad to see the T1 connection with asterisk. Please help. Please see my other post:
