Hi @denniszitha

By having a quick look at your capture I can be fairly certain that one of 2 things is happening. The 200 OK from FreePBX never makes it to the PBX (it makes to the NIC of the server but not to the 3CX) so the call is never established so you do not have any audio or them more likely scenario that the IP the response is coming from is blacklisted so the PBX ignores the reply.

Check your blacklist for that IP (or a range that includes this IP) and delete the entry if necessary. You may also try disabling the global blacklist and try again in case it is included there for some reason.

Hi Yiannis,

You are very right after removing from blacklist audio is working perfectly.

Thanks alot...
