[Asterisk-Users] SIP Message Extension support

[Clif Jones]

Hal,

This has been discussed before: 
http://lists.digium.com/pipermail/asterisk-dev/2004-February/003052.html
Basically, a handler for the MESSAGE and INFO messages would have to be 
written and they would have
to utilize Asterisk's registration data and then "proxy" these messages 
instead of terminating them.  Right now,
Asterisk works as a SIP B2BUA so one call is actually 2 different call 
legs with Asterisk being common to both.
The above messages must be relayed from one call let to another.  The 
INFO is needed so you can get those nice
"Hal is typing..." messages at the bottom of your messenger window.
