[Asterisk-Users] SIP "PUBLISH" and "SUBSCRIBE" extensions?

[Ulexus]

After having received my brand new SNOM 200 phones and trying to get the 
remote extension monitoring to work, if seems that they use the "SUBSCRIBE" 
and "PUBLISH" SIP methods to do this.

Further, doing a swift grep of the asterisk code, I don't see anything like 
this in Asterisk.

Has anyone heard of anything about anyone working on this?  Mark?
