asterisk users - Aug 2007 - Incoming and Outgoing zaptel configuration : ISDN30e

We are trying to configure a Sangoma A101 card to allow both incoming
and outgoing calls on a UK (BT) ISDN30e line with only 24 channels
enabled.

At present incoming calls work fine. We can't call out -- we get a
BUSY/CONGESTED error.

Do we need another context in our zapata.conf? In other words, do we
need to reserve, say, channels 17-24 for outgoing calls? I also wonder
if the signalling type for these channels should be changed.

I would be very grateful for any comments.

Regards
Rory

What is your dialling plan command for outbound calls ?

I think that your

channel => 1-15,17-31

should be

channel => 1-15,17-25

  channel => 1-15,17-31
Is telling Asterisk that you have 30 active channels. Change it to:
  channel => 1-15,17-25

And you should be sorted.
