I have tried every combination of unknown, national and international with
every combination of number length. I have also confirmed that by using
wanpipemon to capture the D-channel messages. When I went through them
with Wireshark and compared them with Q.931, everything was being set correctly
by the Sangoma card/drivers. I am at the point now where I need someone
who has worked with BT ISDN switches to tell me what they can accept. It
seems that this is a national secret over here, or instead that they can accept
almost anything and my lines have been configured to override the outgoing
calling number with the base number. Either way, the only way in which I
think I am now going to get a result is by booking a fault. Your helpful
comment about modern switches being able to work this out also confirms that I
am probably not looking at a Q.931 formatting error on my part, but on a
blockage in the exchange. I don't have a problem with the called number,
for example.<br>

prefer to use Called and Calling – The numbers contain a few bits that
tell what number this is. The most common are unknown, national and
international. These bits must match the actual number you send. The 10 digit

top of that you will face that modern switches are quite capable and able to
configure whatever behaviour they want per line with regards to called/calling
– so you need to find out exactly what the switch expect on both called
