Can anyone tell me the best way to interconnect a KX-TDE200 (with DSP-64 and 16 IP trunk licenses) to a Panasonic 576HD with only analog trunking? I would like them to be able to dial between sites over their new super-fast comcast connection. I was thinking an audiocodes gateway at the 576HD location, but not sure if I have the right equipment at the TDE site. Thanks!
