ATA 190 with FAX

Thomas P
Level 1
Level 1

Hello,

I have a fax (Brother FAX-2920) connected to an ATA 190 and I cannot send or receive fax.

My CUCM is connected to the PSTN gateway with a SIP trunk.

FAX==>ATA190==SIP==>CUCM==SIP==>2911PSTN-GW==>E1

 

What I have done so far:

-Reduced the baud rate to the minumum on the fax machine

-Enabled the option Fax Error Correction Mode Override on the ATA port

-Collected some traces with RTMT. The debugs show that the CUCM does not received all the digits dialed from the fax machine. For example, if I dialed the number 00123456789 from the fax machine, on the traces I see that the number 001345789 is dialed or 0012345678 and so on...

 

Could you please help me with this issue? I'm running out of idea.

 

Thank you in advance.

 

Thomas.
