If you are using IAX2, you don't need to port

Just have PBX2 register _often_ and that will keep a

Where is this set? Is this the minregexpire and
maxregexpire settings in iax.conf, which default to 60
seconds? (And what's the purpose of the "min" and
"max"; why isn't there just one setting, simply
"regexpire"?)
And is the default of 60 seconds considered "often"?
Finally, what's the difference between registering
often and setting qualify=yes?
'Often' is often enough for your Nat router.
60 secs seems enough for the ones I've used.
If I recall it right:
Qualify sends an IAX POKE, (expecting a PONG) whereas
registration sends a full REGREQ which requires more
processing power at the far end (typically a database lookup
of your user name and an MD5 of your password) and an extra
2 packets to complete the exchange.
You are 'encouraged' to qualify, but I like to register, mostly
out of habit I suppose.
Tim.
