Ok here is the problem at this time we have a Partner System and we have a radio patch plugged into it to we can call over the radio channel from one of our phones.I am getting ready to install the Merlin Legend System on Sat. and i have tested everything else and this is the only thing that does not work.When i plug it into one of the extensions on the 012 Module and i call it i can break into like i should be able to but i have no voice.I don't know if anyone here has encountered this problem or may or may not be able to help me but if you can please leave a reply.
