Yeah, I just researched it further on the forums. We have a lot of VoIP customers. I am surprised that we haven't received a single complaint. The uptime on these radios are over a year though. I'd love to be able to use back-to-back frequencies, or to not have to have such large guard bands in between freqs. However, there is no way I am going to do a complete forklift of the entire network at this point. I am not the only one creating noise. There are at least four other providers in this area to contend with. I will have to investigate this further and see if I can move some channels around to resolve this. Thanks for the heads up.
