asterisk users - Jul 2004 - quadbri NT_mode S-Bus Problem

I am running * with a Junghanns quadbri that should allow us to integrate
our ISDN house telephone system with VOIP. Preferably I would like to run a
setup, so that our internal ISDN phones on an S bus are not aware that * is
sitting in between. 

 

With the configuration below I run into the following problems:

 

1. On outbound calls, I get the normal rining call progress tone althought
the the other party has not even been reached. This then changes from normal
ringing suddenly to busy when the other party is sending a busy signal. I'd
rather have the call progress send a busy signal right away.

 

2. Internal calls between to ISDN phones on the S-bus is not possible. The
phone rings but the call is dropped as soon as it is answered.

Can the signalling= bri_net_ptmp be the cause and how would I configure it
for bri_net?

 

Does anyone have a working configuration that overcomes thoses problems?

 

Regards,

Ben

What type is your "ISDN house telephone system"?
Without more specific information all we can do is guess...

For a sollution to 1 ... drop the "r" option of dial...
exten => _X.,1,Dial(Zap/g1/${EXTEN})

You might need pridialplan/prilocaldialplan set to local for local 
calls... or both to unknown... just experiment with those values.

Our system is a just the basic subscription to SWISSCOM, which is the main
phone company in Switzerland. We have BRI with 2 Channels which can be used
simulaniously and a Siemens NT that has only the function of feeding our
S-bus with 4 phones connected.

I will give it a try.

I am still looking for any documentation regarding the use of
pridialplan/prilocaldialplan. I don't know how to find out what SWISSCOM
requires.

Thanks for your help.

I gladly look at your config files to see what I have done wrong. At the
moment the setup is hooked up that I can make inbound and outbound calls
(from ISDN and SIP clients), just with the limitations as below :

1. On outbound calls, I get the normal rining call progress tone althought
the the other party has not even been reached. This then changes from normal
ringing suddenly to busy when the other party is sending a busy signal. I'd
rather have the call progress send a busy signal right away.

2. Internal calls between two ISDN client phones on the S-bus is not
possible. The phone rings but the call is dropped as soon as it is answered.

Kind Regards,
Ben
