Detecting Fax Tones over IAX2

Report
Question

Hello All,
I use IAX2 as the incoming connection from my DID provider. For whatever
reason, this works best for me, SIP connections lag very frequently and
only have about a 50% success rate for incoming calls (they get dropped
mysteriously). I'm trying to implement a fax/voice switch. I have faxdetect=both in my
sip.conf, and when I use sip, it works well. However, from what I can
tell, there's no such option for IAX2 connections. Any ideas on what I can do here, or am I out of luck? Thanks,
Cody

SIP endpoints CANCEL when PRI receives Cause Code 31

Question

We have an Asterisk server which connects to another Asterisk server
acting as a PSTN gateway. This gateway machine has Digium TE210P card
connected to a pair of PRIs. For the most part, all is working well, however there are some specific
telephone numbers that my users have attempted to call, but we unable to. I set debugging on and determined that when the the gateway machine
dials one of the numbers in question, we receive from the PSTN an ISDN
cause code 31, which in my understanding is not an error. This is then
