Nicolas,
I don't know how far in Asterisk you are trying to support, but I have an old PBX which is running Asterisk 1.4 - iax2 show peers displays OK for any active IAX2 extension. FOP2 should be able to monitor that.
I am sure that FOP2 can determine the version of asterisk that it is running, and determine how to handle IAX2 extensions accordingly?
Hi, FOP2 does not use the console. It uses AMI. AMI integration with IAX is, as I said, flacky at best. Are you using Asterisk 1.4? Grep "manger_event" on chan_iax2.c and compare to asterisk 1.8. Even in 1.4 I think there is no IaxPeer manager command (I do not recall, it's been a while I am not looking at 1.4 installations).
