SIP FAX gateway

Unanswered Question

Hi all, I have what I think is a simple question.

I am exploring the IOS FAX capabilities and I needed the following:

I have a software that enables me to send faxes through SIP, on the other end I need a gateway that will receive this SIP call and then forward that FAX call to POTS, thus sending a FAX.

Is there any feature in Cisco IOS that enables this? I've been looking at IOS SIP T38 gateway but I'm not sure that this is the correct option.


I have this problem too.

Yep; T.38 would be the correct protocol to use. Here are the documents on fax and SIP gateway configurations.
