Summary:                    Peers become unreachable when 'sip set debug' is
enabled and reachable again when 'sip set debug off'
Description: 

I have two Asterisk boxes. One contains a 'type=friend' entry in the
other's sip.conf as follows:

[asterisk-b]
username=asterisk-b
secret=asterisk
type=friend
canreinvite=no
nat=no
dtmfmode=rfc2833
disallow=all
allow=alaw
allow=g729
context=from-asterisk-local
deny=0.0.0.0/0.0.0.0
permit=172.16.0.0/255.255.255.240
host=172.16.0.4
qualify=yes
insecure=very

(the bug applies if 'host=dynamic' also)

If I turn SIP debugging on, after a few moments, Asterisk says that the
host is unreachable. As soon as I turn debugging off, the host becomes
reachable again.

This is 100% repeatable and when debugging is off, there are absolutely no
communications problems at all and the peer is reachable all the time.

Interesting, enabled sip debug doesn't really change handling... it just
outputs the packet with some info to the CLI (which could introduce some
delay...). Can you also provide a tcpdump/wireshark/ethereal dump on port
5060 so I can see the packets coming back? (with and without sip debug
enabled)
