Client calls into his 3cx phone system from his cellphone and gets busy signals often.

[Aaronb160]

Recently I’ve had a lot of reports about a client trying to call into his 3cx phone system from his cellphone and he occasionally gets busy signals. I’ve found the call in the activity log (in verbose mode) but I’m having trouble understanding what the error is. Here is a attached picture of the call. Any recommendations on what I can do to troubleshoot this issue? I’m still new to 3cx so please pardon the vagueness of the question and let me know what other info I may need to provide to figure out why this keeps happening.

Please provide more information.

Is it just this one individual that reports the issue? You say they are calling in, but where is their call supposed to go...a DID/extension?

If so, does anyone else, calling the same destination have problems? Do they have issues calling another destination? If he calls in from another phone line, is there the same issue?

And, as mentioned, you really need to provide more information about your installation.

The information requested by Frederick and leejor will indeed be required. Also, at the time the issue occurs, check if internal calls work for that same extension.

For instance, if a external call was supposed to reach extension 13 (as per logs) but got a busy signal, immediately have an internal extension call that same user (in this case ext 13), does the user receive the call okay?
