Dear All,
Here is the call flow for failed fax :
ATA 187---------- CUCM 8.5 ----------2951 SIP CUBE------------ITSP
We have SIP link and a CUBE router, everything is working fine apart from the fax. Can someone please give me some sample config

Well, I would say, if they support t.38, then use it:
dial-peer voice 1 voip
fax protocol t38 ls-redundancy 0 hs-redundancy 0 fallback pass-through
fax-relay ecm disable
fax nsf 000000
fax-relay sg3-to-g3
Configure ATA to t.38

Hi,
You can just add ATA as a device/phone in CUCM and use the existing dial-peers for other phones.
Fax Mode "Fax pass-through" worked perfect for me on both ways and I needed to have
!
voice service voip
fax protocol pass-through g711ulaw
!

First of all, you need to clarify what faxing protocol is your ITSP supporting, Pass-Through or T.38.
If T.38:
CUBE Dial-peers:
dial-peer voice 1 voip
fax protocol t38 ls-redundancy 0 hs-redundancy 0 fallback pass-through
fax-relay ecm disable
fax nsf 000000
fax-relay sg3-to-g3
Configure ATA to t.38
If Pass-Through:
CUBE Dial-peers:
dial-peer voice 1 voip
fax protocol pass-through g711ulaw
Configure ATA to Passthorugh.
Please make sure MTP is not allocated for fax transmition, it will break it.
