Can someone list all the ports that need to be open per MCP and MGI? We can call from node to another, but not the other way. I am using the long hand method to bypass the routing.Also, wjen we do connect, there is no audio or talk path.

Here is a link to a former topic in this forum that should help you.

Thanks, I saw that one the other day. Some say 9000 and 9001 should point to the MGI.

Try a cold boot on the routers and phone systems.

I wil try that. We have made quite a bit of port changes on the sg300 router

Turns out ping was turned off on 2 of the nodes/sites. All is well now
