We're testing phone proxy for a new customer. We have about 10 devices working fine. But, a few are having some problems:
1) One location has 2 phones behind an Edgemarc device. The phones are experiencing one-way audio under certain circumstances. We ended up setting a static NAT to one of the phones and now all seems fine.
2) Another user has reported that after 15-17 minutes audio drops to one-way and/or the remote user is put on hold. If they press the hold button and then resume then the call is fine. This has happened from 2 locations with SOHO routers. We're going to try putting the phone in the SOHO router's DMZ to see if the problem continues. This could be a bad phone.
Both of these issues seem to be related to NAT on 3rd party devices. Phone proxy states that it's compatible with one or more devices behind a 3rd party NAT device/FW however. We're still working through different scenarios for the above two to narrow down the problem.
Is anyone else having NAT related issues and what is the resolution?

the softkeys. You enable or disable them via TCL. Here is the long
