Before we do, could anyone confirm for me that BT's
ISDN2e lines do
actually provide Asterisk with the DDI number? We need to
be able to
route incoming calls based on which number is ringing.
Yes they do. For DDI ranges you'll need to ask BT for a
"System Access"
installation (sometimes known as "Point-to-Point") and
configure the
Junghanns appropriately.
I'll have to check that, I guess - find out what they're set as!
I'm probably just an old fogey with a programming background, but I
find straight Asterisk *so* much easier to configure than [EMAIL PROTECTED]
True, I've used bare Asterisk at home for my small get up,
but [EMAIL PROTECTED] just does everything we need it to do here at the
office (including the "nice and pretty"
call log side of things that AMP provides!)
When you say "ringtones", do you mean "sounds like a UK
phone when it
rings", or "sounds like a UK phone when we ring someone else" ?
It does actually sound okay when we ring someone else, but
when it rings, it has the long single american style ring.
I've come across a few places that claim its built into the
Grandstream and I'd have to create and upload a new one..
but I've also found others that say to edit various config
files, which has had no effect (indications.conf and
zaptel.conf both have the zone as uk.. Theres nowhere else it
needs to be set, is there?).

Try adding the following to your handset config in sip.conf.

You described this so much better than I did. IIRC, the first
10 MSNs are contiguous for point to multipoint. After that all
bets are off.

Our recent PTP installations have turned up without CLIP but
with COLP. YMMV, it seems...
