hooking the X100P to the modem's Phone port.

From what I've been able to determine, Asterisk would be most unhappy if you did that. On X100Ps that "phone" jack/port needs to simply be ignored. I have a telephone connected to mine, but it's only there in the off-chance of an emergency, power outage, or to troubleshoot problems with the FXO.


Can I enable fax detection and use the fax extension to spawn an
external
command (halafax) to receive the fax?

Uh, well, in the obvious way yes, but not in the way that you seem to be wanting to hear.


exten => s,1,Answer
exten => s,2,wait(5)
exten => s,3,....
exten => fax,1,Dial(FXS_PORT)

Where "FXS_PORT" is an FXS port where a HylaFAX-controlled modem is connected... or any other fax device for that matter.

The problem is, though, that there seems to be a significant amount of data loss when receiving with this configuration... even using ULAW. Now, an ECM-aware fax device may compensate well-enough, but there's still a problem.

What is the state of fax detection with the stable branch of * on an
X100P? Does it work reliably?

Fax detection is generally okay, but there are some problems. See:
