Fax by SIP Trunk

[brunofalco]

Hello,

I have a CUCM, and a SIP Trunk with Avaya. All the calls are done by this SIP Trunk, and it is working normally.
I have one ATA (Audio Code), that is connected in a Device Fax.

Please, I would like to know if is possible to send a Fax with this ATA using the SIP Trunk!!

Regards,

Bruno

Hi Mohammed,

Tks for the infos.

But I´m using a non Cisco ATA....it is from Audio Code.
And, I´m not using a VG, or a GW.

The call flow is ATA >> CUCM >> SIP Trunk

Is it possible??

Hi brunofalco,

Is AudioCode ATA talking to CUCM on SIP. Should work.

Mohammed ,

But do I need some specific configuration?

I have created a SIP Trunk, SIP Profile, sip trunk security profile....

MTP should be unchecked
