Kamailio is a signaling SIP proxy and it doesn't deal with media.
Fax negotiation belongs to the media endpoints.

PS: BTW, detecting CNG as a fax tone is a bad habit.  You need to
detect the V.21 tone for fax transmissions and if you have fax
machines dealing with v.34, then things become more complicated.
