I have a hosted VoIP service to a 3rd party provider (they are run 3CX servers). We have a few public T1s back to their network to cut down on latency running through a 2821 running the latest 12.4T image. At random times phones and calls just drop off and will not reconnect. I am thinking this is a NAT issue as when we setup a GRE tunnel there are no issues and all phones work. Are there any commands I can run on the router to improve NAT when SIP is concerned? Do I perhaps need a different image to improve SIP? I didn't think so initially as we aren't doing anything special from our end, just mainly connecting to the provider.
