Unable to make internal calls to extensions

[TLITPGH]

When trying to dial an extension (ie: dialing 101 to reach another user from extension 100) The call says it has failed and to contact the admin. I can't seem to track down the exact issue but the things I have been seeing on the forums so far indicate it may have something to do with our outbound rule. Does anyone see an issue with the configuration here or know why this may be happening? Thanks!

A server error 500 is generally bad. There's something wrong with the system or an infinite loop or some other impossibility has been configured.

If 3CX uses a 3-digit extension number no outgoing rules are initially applied unless the called user has a forwarding feature set up somewhere (in the worst case, directly on an IP device outside of 3CX).

Please describe 3CX and the environment you're using in more detail.


Also, is it safe to assume the issue wasn't there from the beginning? Has this worked before? What was changed?
