Did you ever get a resolution for this issue? I am running into the same problem.

Thanks,

Hi Aslam,

First of all, you need to clarify what is the complete call flow and all devices that are part of it, so we can have a better idea on what we are dealing with.

Please take a look on the following document with the most common Faxing supported call flows:

https://supportforums.cisco.com/docs/DOC-25210

You also better not use "fax protocol cisco" under voice service voip, it's kind of legacy FoIP procotol now a days.

We know that you have an H323 GW receiving the calls, what about the end device? Is the fax machine connected to a different router?
