Summary:                    Duplicate SIP 180 / Ringing Messages in SIP trunk
ingress
Description: 
Have a SIP trunk and a single SIP peer.  When generating an inbound call, I
am seeing duplicate 180/Ringing SIP messages.  Carrier is complaining about
this.  SIP trunk setup is:


[NBS]
qualify=no
ignoresdpversion=yes
nat=no
host=205.x,x,x
reinvite=no
dtmfmode=auto
context=from-outside
type=friend
insecure=port,invite
canreinvite=no
disallow=all
allow=ulaw
allow=g729

Peer is:

[101]
qualify=yes
nat=yes
pickupgroup=57
callerid= Demo <101>
context=from-inside
canreinvite=no
vmexten=101
secret=xxxx
host=dynamic
username=101
subscribecontext=local-extensions
callgroup=57
dtmfmode=rfc2833
type=friend
mailbox=101 at default
disallow=all
allow=ulaw

(02:02:19 PM) jcolp: they might have that 'r' option set on Dial so it
tells the SIP channel to send ringing, which it does
(02:02:32 PM) jcolp: and then later it gets told again to send ringing,
which it does, again
(02:02:45 PM) jcolp: (although it shouldn't, since it already did)
