A simple first step would be to pick a known good fax number and do some testing. I would first call it from a cellular phone as a control and make sure you get a fax tone. Then try to send to that number from the fax machine behind the ATA. If that fails, I would take a test set and plug in to the ATA and call the same number from the test set. If the call succeeds on the test set and you hear a fax tone, the issue is with the fax machine configuration/compatibility. If the call fails, the issue is with your CUCM (or whatever call agent you use), your dial plan, the PSTN, etc.

I would recommend you do some troubleshooting first. Check the logs in CUCM and/or GW/CUBE.
Nobody will be able to help you, with what you have written in your question.

Why don't you just check the logs?! This is the first step in troubleshooting. This is your task as a technician and nobody can take it away from you.
As said, nobody will be able to help you without having insight to the logs. It is just guessing, what might be the problem and what might be one possible solution?

sorry @b.winter I forgot to reply. I've checked the logs yesterday and as @mradell he suggested I gone thought this way and found that problem with pattern. thank you so much guys it got resolved

 

once again thank you @b.winter @mradell
