voip drops calls at 30-32 seconds, but only toll-free numbers

While this could be some sort of NAT issue, I am already port forwarding the RTP ports to my device so that would not be the cause. In the 1.5 years I have had this BYOD setup I've never run into NAT related problems before with any of my calls. I also have a second provider on my device and have not had any NAT problems with that line either. And it's also strange that using a different provider to route the TF calls through with the exact same media server works fine.

Tim can you test this on your side by calling a TF number and seeing it route through this particular carrier (207.223.64.xxx) using the sip-west01.voipwelcome.com proxy? If it works fine on your side then I would agree that it's most likely something with my setup, but I would be curious to know if you can reproduce the problem.

same issue, i am running asterisk 1.6. toll free call to 1-800-999-3355 gets dropped after 30 seconds. no issues on any other calls. looking at logs seems some kind of reinvite issue.. any suggestions on sip.conf configuration for voipo would be appreciated. I am not behind NAT

We're not able to replicate this issue with any of the devices we provide.

The commonality seems that all of you reporting it are using Asterisk or some form of BYOD.
