LightSpeed: Since no one has responded to you as yet, I will try.

I have not done the SIP yet, so anything I say you will want to verify.

I believe that just having a BCM-400 may not be enough to use SIP. You need the correct version of software (or maybe a BCM-450?? )
Which version do you have?

There are different licenses.
There are IP Phones.
There are VoIP Gateway Trunks.
There are SIP Gateway Trunks.

So you should check with your Nortel BCM sales Rep to order the right license.


If CON is the opposite of PRO
Then what is the opposite of Progress?
