Reason of the CANCEL

[hunger]

Dear team

Could you please advice for this behavior most of the outbound calls getting dropped. When we check with ISP they're getting blacklist our caller ID frequently
due to the reason of most CANCEL sent in this traffic frequently.

How can we find this reason of CANCEL is it from 3cx Server?

Who has 192.168.14.17 and who has192.168.14.21? Since his would appear to be between an extension and the 3CX server, have you looked at the same information between 3CX and your VoIP provider? Have you looked at the 3CX Activity log (Verbose)?

What is the reported issue, with your caller ID, please explain.
