I'm not totally sure what you want, but I'll give it a shot:)

Multiple SIP registrations are not (yet??) possible, even though this is 
described in the RFC. Also see bug 157. Hopefully this will be 
implemented in chan_sip2, this is bug nr. 759.

What you can do is:  
Dial(technology/extension&technology2/extension2&technology3/extension3) 
or code it yourself (or put a money bounty on it).

Kind regards,
