Hello Everyone,
My first post on this forum...
I have a CUBE that sits in the middle between my VoIP network to the ISP.
Our fax machines, currently, connects to analog voice gateways (VG224, etc), and are using T.38 throughout our organization.
We are trialing SIP Trunking from one of our providers, but they do not do T.38; only pass-through.
Can we not terminate the T.38 at the CUBE and have the CUBE initiate a passthru to the ISP? sorta like store-and-forward on the fly? I can't seem to find any reference to confirm if this is possible or not possible. Ultimately, I think this will be a deal breaker for us to move to SIP trunking.
*** Don't ask why we are still doing faxing today... *** --facepalm--
Cheers,
Trev.

Hi,
“Fax Passthrough” refers to the passthrough transport method using an NSE switchover to pass faxes over G.711. In Fax Passthrough mode, gateways do not distinguish a fax call from a voice call. Fax communication between the two fax machines is carried in its entirety in-band over a voice call. It only support G.711. CUBE does not support transcoding of T.38 to G.711. For T.38 to work on your fax machine side, your ISP must support T.38. Or you need to change Fax protocol on your fax machine side to match with your ISP.
