I have a summit 80 that works perfect at the California location with 13 sip lines. I installed 5 Voip phones to the summit 80 in Arizona. The phones register in California on the Summit 80 and work as they should except for the following. You can use 2 of the lines in California with no issue. Calls come in and call out great. These two lines are located on the VOIU card. The 11 sip trunks located on the VOIB48 board have no talk path, when you make a call or receive a call you can answer it and see Caller ID but no talk path. Any suggestions?
