Changes
-------

Trivial update, getting this to show up on -dev


Summary (updated)
-------


This is a patch to trunk which implements the subset of RFC 4474 suitable for 
asterisk calling number authentication.   It can sign SIP INVITEs and verify the 
signatures of incoming INVITES.  The current implementation implements much 
of the RFC. The result of the signing and validation is placed in a channel 
variable ( IDENTITY_RESULT )
for dialplan interpretation. This allows the dialplan to authenticate the 
CallerID and prevent SPIT.

The private keys for signing are taken from 
a local directory, a cache, or an http server. The private key is used 
to sign a digest string. The certificate is retrieved from the location 
specified in the Identity-Info header, or from the cache, if present. 
SSL is not currently supported. 


This addresses bug 0016187.
