I'm hoping someone can help stop beating my head against the wall. I have two REDs connected to our ASG220 and each RED interface has an IP phone. They can talk to anyone in our facility just fine, whether it is an digital PBX phone or and IP phone. Once they try to call each other (RED interface to RED interface) the phone will ring (since the phone system in-house manages call control) but if the other person answers (on the the RED segment) they can't hear each other.
Also, I've confirmed that the call is not being dropped.
Any ideas?
