dead air / fasty busy service problems

[VOIPoTim]

Dead air is almost always related to port forwarding not being setup. The audio streams come from third-party provides and NOT from our system so a lot of routers don't think they are legitimate and block them.

We do now recommend 5004-65000 since that range covers all the ports our upstream providers use.

I know it sounds repetitive, but most routers block the traffic and we see this constantly and see forwarding resolve the issues with a very high success rate.

I'd recommend verifying the port forwarding and if that is setup and it's still not resolved, send the router model numbers to support for further assistance and they can tell you what else would be causing it.
