I've recently decided to go with Nextiva for voip service, I'm using their system, but due to needed customizations, I'm using my FreePBX system for the PBX Automation.
I've set up trunk as follows:
I asked their tech support about the issue, and they told me I needed to set the register expiration timer to 60 seconds. I assume that is defaultexpiry, which is usually set to 120, so I changed it and verified that every 1 minute the service is reregistering.
I do receive an error in log and not sure why, error:
<--- SIP read from <nextiva_ip>:5060 --->
SIP/2.0 403 Forbidden

Maybe have something to due with "Unknown" / or need to send some credentials with request? Not sure how I would do either one of those things.
When I first start service, works great, can receive calls and send calls with no problems. After connected for a while (seems like around 10 to 15 minutes), the incoming connection dies, but the outgoing connection is still functioning.
I can verify that Asterisk is reregistering every minute (like I was told was needed), but connection still is dying...
Any hints on what could be the problem? or anyone who get Nextiva service to work with FreePBX?
