[asterisk-users] ISDN

[Michael Graves]

I had converations with both Pika and Xorcom wherein the thought that
it should be possible using their interface hardware. There might be
some software changes to be made in their drivers, but BRI should be
usable in the US.

I abandoned the idea for being more expensive when all costs are
considered.

I have done this.  Why BRIs exist in the US is beyond me.  If you can,
don't go with BRI.

Who is the carrier.  There is someone on the list that will tell you it
is impossible unless you use his code, which is not true.

Thanks,

I had considered something like this as well, but was convinced to go
another direction. 

I wrote something up about it at the time.

Hi, 

I'm in the process of setting up Asterisk in a SOHO environment using
ISDN for trunking. More specifically a BRI 2B+D circuit where one SPID
is used for the business and the other is used for personal. The
circuit already exists, but is presently being interfaced to POTS
phones via a TA. 

This configuration is not very common in the US, but we are fortunate
that our LEC offers it price competitively with equivalent POTS
services and it makes more sense, both in terms of voice quality (4
wire digital to the PABX) and flexibility. 

Ideally it would allow any combination of two calls, identified by
SPID. 

If anyone has done anything similar, or has any experience with BRI
ISDN, I would appreciate input and direction. 

If anyone knows where documentation exists on configuring ISDN, that
information would also be greatly appreciated. Asterisk has a bit of a
learning curve, and ISDN BRI isn't the most widely used or covered
aspect of it. BTW, I have a strong telecom background, so the theory
part of it will not be a problem, only the necessary documentation to
apply it to Asterisk. 

Thanks,
