Summary:                    Qualify intervals >1000ms create needless double
OPTIONS transmissions
Description: 

If "qualify=" is larger than 1000ms, then the re-transmit interval (T1)
should be much higher, either whatever qualify= is set to, or the last
value that was returned from the OPTIONS query.  Otherwise, the one-second
default timer triggers another OPTIONS transmission, which doubles the
amount of traffic to the peer every interval.

Okay, I'm looking at this again, and I'm not seeing where the options is
retransmitted once a second.  The OPTIONS packet is by default only sent
once every 60 seconds, when the host is up, and once every 10 seconds, when
the host is down.

I also see that an OPTIONS request is sent whenever Asterisk receives a
registration attempt, so is it possible that your phone is not registering,
but you have a defaultip defined, and each registration attempt results in
an OPTIONS packet?
