[Asterisk-Users] IAX2 echo cancellation?

Hey all,

Does IAX do any sort of echo cancellation?

I'm still trying to get faxing working via an IAX peer (from a faxmodem
hooked up to my Sipura -> Asterisk -> IAX Peer -> PSTN Fax), and one of
the things I've read may be necessary is disabling echo cancellation. I've
disabled it on the Sipura, and my faxing success rate has gone up (About
1/3 faxes go through successfully now), and I'm wondering if IAX is doing
any echo cancellation that I can disable.

Pointers to relevant documentation would also be appreciated.  :)

Thanks much!
