VPN question, related to PRI

By gli ·
We have a main office and two branch offices. We connect to the branch offices using Point to Point T1's. We are using PRI T1 for our phone service, manages by a Nortel BCM400. When we need to phone the branch office we use a 4 number extension.

Now, if we switch over to SDSL or SHDSL or even just Internet T1's for each location and then VPN everyone together, can we still just use 4 number extension to communicate over the PRI phones?

I was told by someone that PRI only works over Point to Point T1's.

Thank You

It shouldn't be a problem

by Oz_Media In reply to VPN question, related to ...

I can't remeber with the BCM400 (it's been a while since I have installed a BCM) but I THINK you will not have a problem. PRI is PRI, the only limitation will be found in the switch, and I am pretty sure Nortel's digital line card accepts PRI with 4-digit extension dialling.
I've seen a few other switches that won't though and if I remember correctly it was a big hurdle for the BCM with the 2.5 software (really botchy first release) and the NEAX IVS 2000.

Contact NORTEL.
