Jose,

Does your ITSP guarantee T38 to all numbers?  I know most ITSPs can't do this and only can do T.38 to some numbers.

Hi all. Does anyone have found a recipe for running faxes through ATA 187 when using SIP all the way? The scenario is as follows:

ATA 187 - CUCM - CUBE - ITSP. The entire path is SIP up to the SP. We have tried all possible combinations from turning ECM off, reduce speed to 14,400 both of them in the fax machine, T.38, NSE g711 passthrough, passthrough both in the cube and in the CUCM, etc ... and fail to achieve the exact recipe for all outbound faxes work. some destination phone numbers work and other particular numbers do not work. All inbound faxes work well. The fax machines are a multifunctional Ricoh MP4000 and worked previously with the carrier using POTS. please help!

Regards,
