Summary:                    MWI not working for most ATAs
Description: 
After upgrading several (around 20 or so) customers to our new Asterisk
server running version 1.6.2.17, most of them are complaining that their
MWI no longer works. I've tested this with a variety for ATAs, and so far I
can tell that these ATAs do not get a message waiting indicator:

Thomson 780 and 784
Linksys SPA2102
Linksys PAP2

One ATA that I can verify *does* work, is an old Sipura SPA2002, which of
course, is out of production. I've worked extensively on a Thomson 784
trying to get the MWI working, but to no avail. As far as I can tell (with
the use of sip set debug peer on the Asterisk console), it doesn't even
send the SIP NOTIFY message for the MWI.

D'oh! 

Well, the configuration is uploaded now, and so is the SIP trace.

I see from the SIP trace that the NOTIFY: Messages-Waiting message is
getting sent, but why are none of the clients getting these messages? In
this particular example, the ATA is connected directly to the internet (the
Thomson 784 is an all-in-one router/DSL modem/ATA, and the ATA is not
firewalled or NATed). 

Is the NOTIFY properly formatted?
