Hi i have a Merlin plus. What i am wanting to know is. We have several different adapters. Like the BTMI2 and the GPA. Now where i run into problems is before i had a Cordless Phone plugged into one of these BTMI2 adapters and it worked fine for awhile then all of a sudden when i go to use the phone the intercom is all garbled up and the minute i try to call another EXT it makes a error/busy tone. So since it does that i started using a GPA and plugged into one of the VT and now it works fine again. Can you help me figure out why it does this and what is possibly causing it. I have 4-5 of those btmi and it does the same on all of them. Thanks
