Hi,

I use Fax on PAP2T with FS successfully for a while now.

My Config is like this:

Fax on LINE 1

Preferred Codec = PCMA aka G711a		
// Valid for Germany ;)

Use Pref Codec Only: yes
FAX process NSE: no
FAX Disable ECAN: yes
Silence Supp Enable: no
Echo Canc Enable: no
Echo Canc Adapt Enable: no
FAX CED Detect enable: no
FAX CNG Detect enable: no
FAX Passthrough Codec: G711a
FAX Passthrough method: None
Call Waiting Serv: no
Network Jitter: high
Jitter Buffer Adjustment: up and down

On the Regional page:

All three Polarities: Forward
FXS Port Input gain: -3
FXS Port Output Gain: -3
FXS Port power Limit: 3
FXS Port Impedance: 600		//Germany :)
More Echo Suppression: no

That works on my side.
