This seems like a non-standard way of doing it, putting the 
authentication information into the CC-Diversion header. IIRC, 
CC-Diversion is meant for call redirection, such as call forwarding and 
divert to voicemail.

Reading the excerpt, it seems like you'll have to do:
Set(${CALLERID(num)=7325551212)
SIPAddHeader(CC-Diversion: sip:19174391018 at sip.sipmedia.com:5060)
Dial(...)

Hope this helps.
