Sip Autodestruct Error (100% down!!!)

[bondkmf]

I replied to an older thread but it is getting no attention. My version and build are below.
The problem is that my 2 asterisk servers will appear to be working fine then all of a sudden no one can complete a call.
Here are some of the errors:

I am at a complete loss, even after I reboot the server it will work for maybe 20-30 mins then it gets flooded with this error again.
Please help as we are 100% down.

This is my carrier dial plan and we have switched carriers and that didn't help either.

Turns out we were saturating out new 20Mbps fiber connection...Switched back to a 350/25 Coax connection and problem went away.
Figured I'd post this in case anyone experiences a problem of this nature in the future.

Any ideas on how to not fill our full 20Mbps fiber? Codecs? Separate internet lines from VOIP lines?

Any input would be greatly appreciated as we are paying an arm and a leg for 20Mbps of fiber and was told that should be sufficient for out 50 agents.

Are your agents on a local network to the calling server? Perhaps line ratio is a bit too aggressive?
Sounds like you have a couple connections, take a look at a load balancer / network bonding device and you can use both Internets.

Thanks for your input.

I will most likely put 1 48 port switch on coax, and the fiber connection on the other 48 port switch.
Even though I would like the entire office to be on fiber.
