[Asterisk-Users] Strange T1 Problem - FIXED plus new question

[mattf]

Sadly it's a limited to PRIs(at least that's what I've been told) You just
can't send that much call data with a good old non-PRI T1. The up side is
you get one extra voice channel to use as compared to a PRI. It's strange
that the carrier doesn't have PRI cabability, I've run into many more
carriers that can't do non-PRI. I've even had one that couldn't send me
ANI(CallerID) on non-PRI lines.

Once you get into the world of ISDN and PRI, you start to be able to do a
lot more with the signaling of calls, and you even have the ability to do
faster call switching as compared to a non-PRI.

My advice is to get a different carrier, there are hundreds out there. And
if you absolutely have to have dynamic CallerID transmission you should
verify that your new carrier will let you do that before you sign a
contract(Make sure you verify it by talking to an actual switch tech from
the carrier, sales people will lie through their teeth to get you to sign
that contract).

Hope this helps,

MATT---

I am getting CallerID and DNIS on the inbound calls. What I really need
is to be able to set callerID on outbound calls. I am trying to set the
callerid using SetCIDNum just before using Dial on a zap channel, but it
looks like the switch guys have it set to always stamp the same callerID
on the my outbound calls no matter what I put in SetCIDNum or what
channel on the T1 I use. Is this a misconfiguration of the switch or a
limitation of the signaling protocol? If its the switch, can you give me
any pointers as to what I could ask them to look for, or if its the
protocol, do you know any other signaling protocol that lets me set
outbound callerID (besides PRI)?
