Cisco ATA190 with Fax over Sip trunk

 

Spoiler
Dear Community Team ,
Hope you all are doing well ,
This time i am facing a problem with FAX and the scnario as following :

Fax machine (HP all in one) to--- analog port of ATA 190 --SIP-- CUCM----SIP----CUBE----SIP----ITSP.
I have configured the ATA190 in CUCM and it's register with (Extension number 650) and seems to be registered properly .

So when I call the Fax number (phone call ) from PSTN to my network i hear a normal phone ring at my mobile.
But when i try to receive fax or send from / to network it fails (it says the number can't be dialed "cisco recorded message").

Here is my CUBE configuration :
(Please note that ITSP support G.711 dtmf-relay rtp-nte & T.38

Try to connect Analog Phone to one of the ATA port and see if you can make or receive calls

Check your Voice dialing first, attach an analog phone to the ATA and make sure you can make.receive calls, then you can move to faxing. 

Thanks nagaraj789 & Jorge Armijo M for your helpfull answers .
It was a dialing plan problem with CUCM .
Now it is working well .

I am having a very similar issue. We are able to make calls to and from the fax machine even. It just isnt sending the fax data or the fax machine gives us a poor line condition error. If anyone has any ideas help would be very nice. I do currently have a case open with TAC as well and our PSTN service provider.
