OK, I could really use some help here. We have one site that we a replacing a Nortel Option 11 with a PBXnSIP solution. Our PBXnSIP will connect to an Audiocodes mediant 1000 gateway. I need to connect this gateway to a Nortel option 11. They connect over an ISDN line. I have the configuration for the Nortel box. I have not been to the customers site yet. I am going next week. Does anyone have any suggestions? Thank you in advance for your time.
