I have a very unique problem, I have more than one trunk in my server. I can’t seem to make call from a particular trunk, the calls are showing as connected in CDR but no sound both way. I can make outgoing calls from other trunks but not from this particular one. I tried using the problem trunk in another server and it works fine.
Please anyone help.
My Freepbx version is 220.127.116.11
Make sure your router is allowing ports 10000 - 20000 for a start, or if you use WebMin make it ports 10001 - 20000, that number is not normally required unless you have extremely high call volumes.
Also inside your truck, make sure nat=yes, this is required in most cases with most routers.
