one way audio after 15+ minutes

[voxabox]

I've been experiencing 1 way audio after 15+ minutes into outgoing calls
I've tried everything except putting the SPA1001 in the DMZ
codeblue was doing great until now
does anyone have other ideas for me to try
TIA

Almost sounds like your router's NAT is closing up on your connection. Have you tried putting a STUN server setting in your adapter? I don't have your adapter model. But most, if not all, have the ability to set a STUN server. Also, some VOIP adapters have a keep-alive interval setting that can be used to send out a periodic blank UDP packet to the SIP server to keep the "hole" in the NAT open.

The Grandstream HT-286 devices that VOIPo will be using have the ability to set either one (STUN or keep-alive interval). I found that with my router, the keep-alive interval setting is what works...as the STUN setting on the HT-286 causes a 2-3 second delay hearing the other party when you answer (I do not have the same STUN problem with the HT-502, so it must be firmware related).

I have been using stun.fwdnet.net as my STUN; keep-alive @ 30
I do agree that it seems to be a NAT/router problem; however, using a VOIPo Express account (registration) on the same ATA worked fine; perhaps, there is a difference in network topologies (Residential vs Express)
I will keep you guys informed

disabling the "Strict UDP Session Control" (2wire 2701) seemed to fix the problem
did 2 test calls without any audio issues
I'll keep you guys updated

53 minutes to (504) 367 XXXX without any problem(;
