Hey guys,
I have an issue that prevents 2 different PBX’s dial internal extensions from trunk to trunk.
I have Trunk A at one location and Trunk B at another location.
Both are connected as I can see the link is healthy but when I dial internal extensions I get a message that the extension is not available.
For example in Trunk A, all extensions are in the 3000 range and in Trunk B are all on 4000.
If from Trunk B I try to call 3001 it says that, that “Your call cannot be completed as dialed, please check…”).
I have setup the Outbound Route but still have this issue.
This is what I find in the terminal, but I cant seem to find the Unkowns.
