Setting up outgoing calls through Cisco UCM to a SIP Trunk?

[phonebits]

Hey everyone, I'm trying to configure a Succession 3.0 switch to 7 and 10 digit calls with an access code of 9 over a T1 PRI to a Cisco Call Manager. The trunk is currently configured to pass 4 digit extension numbers between systems, with the Nortel sending any dialed number starting with 400X to the Call Manager. I'm sort of scratching my head reading through all the Nortel documentation, and can't seem to figure out a simple way to make the Nortel send out the 7 and 10 digit calls with 9 prefixed to let the Cisco server know to send the calls over the SIP trunk. Anyone have any helpful pointers on where to start here?

There is no simple way to do it. It's configured in BARS.

maybe with some finessing you might be able to just move the PRI T1 that's plugged into the telco over to the cisco.....(as a new T1 WIC in one of their gateways)

otherwise a lot of programming changes have to take place depending what you have setup right now.

not sure if you could just change the RDB RLI entry (for PSTN) to be the TIE line route to preserve your dialing plan on the Nortel.

That's what I was afraid of. I have been reading some of the documentation referring to BARS / NARS and it's all Greek to me. Currently it's not configured, the switch is in a lab environment and has no PSTN access. Can anyone walk me through a very crude/simple implementation of BARS that will work for this situation?

Here's some good info on BARS. If you have never done it before it will seem like jibberish to you.

quick and dirty might be dial the access code on the tie route, you might have to dial access code+9xxxxxxxxxx#

and if it's a lab, you might be able to change the access code on that route to be 9, so that way you would dial 99xxxxxxxxxx

first 9 is access code, second 9 is sent to cisco

Reading deeper and deeper into BARS it seems like it would be able to do what I'm trying to do, I just can't figure out how to make it work. I'm thinking very basic configuration with no restrictions etc and a digit manipulation to add the prefix 9 to the digits to be outpulsed. Would it be possible to configure it as if the trunk to the Cisco was a TIE and have BARS think of it as "Local to distant PBX’s HNPA"?
How hard is BARS to set up without all of the restrictions or time schedules, since those are pretty irrelevant having only one route to the PSTN and almost 0 daily calls being sent through the switch? Am I going to have to do manual configuration for every area code and exchange code that might be dialed?

Still trying to wrap my head around this, it's not very intuitive. Basically I want the switch to send (AC1)+NXX+XXXX +9 or
(AC1)+NPA+NXX+XXXX +9 out over the trunk.
