I'm an IP phone novice and need a little basic help. I have a few IP phones deployed in 2 sites to 2 different Definity's. How do I get a 4630 phone in site B to register to the Definity at site A? It keeps trying to register to it's local Definity and coming up with an 'invalid extension' error. I manually put in the IP address for the site A CLAN, but to no avail. Thanks for any help with this.
