Incoming fax T38

[siibi]

Dear Kazoo-lovers,

I have setup a FAX2mail on kazoo.

In the freeswitch logs, I get the following SIP-error : "SIP/2.0 488 Not Acceptable Here"

I read on the forums that T38 needs to be enabled. I tried to enable T38 on the resource documents but without success.

gateway =>

"media": { "fax_option" : true }

After the change, I did a "sup stepswitch_maintenance reload_resources".

Can somebody point me to the solving direction please ?

Thanks a lot ,

Sibi
