I recently upgraded to v12 from v10 and before I have never had problems but since upgrading to v12 people that have verizon (maybe others too) when they call in they can not hear any audio. My representative can hear the caller with verizon but the verizon caller and not hear my representative. I have tested with tmobile, att, sprint, land lines, all are ok except verizon mobile callers. Is there something in this new version that I am missing? I have no idea what to look for. I should mention that this audio problem only happens when calling one specific DID when calling a different DID everything is ok. I have checked settings between the two and everything is the same as far as I can tell, what am I missing? Thanks to anyone who takes time out of their day to help me out.
