Henry,

	1) I know that the SCCP image will need to be a signed image to move 
back from > SIP 6.1 (or something...).

	2) Is the CCM in the other office in a different AS (autonomous 
system), i.e. a different company?  If not, just have his 7960 do SIP 
accross the Internet to your other site.  Might not be good enough (QoS, 
security) for your application, but something to think about.

	3) Here is what Cisco has to say:

	Check out procedure "E".  I think that is what you want for this situation.
