I can relate to that, however when a firewall "is" involved with iax/iax2
connections, one can't generalize or guess at what * might be attempting
without causing service problems, etc. (Installing both is certainly one 
way to do it, except security mgmt always involves shutting down ports
that aren't really needed to reduce exposure.)

I've seen that comment several times before as well. Do you have any idea 
or experience as to what "headaches" might result from its use?

I did have a problem with iaxtel about a month ago and changing to "user"
seem to correct its stability. But, I really don't know whether it was
a root-cause or symptom.

Can anyone help us better understand user, peer, and friend in the iax
and iax2 environment?
