Connecting two asterisk servers and making SIP calls


I was wondering if the IAX2 trunking procedure to connect two asterisk servers can be used to make SIP calls? From the configuration explained here:±+dual+servers it is not clear as to whether SIP users can be make calls between the two asterisk servers using IAX2 procedure. Using this procedure can one SIP user on one asterisk server make calls to a SIP user on another asterisk server?

Thanks in advance.

yes - that’s just how the servers are communicating, the connections at each end can be anything that Asterisk supports.
