You can dial either via IP or by sip device name (the name in brackets
[] in sip.conf).  Either way, you also have to include the username
and password in the Dial statement(). It looks like this:

exten => _5XXXXX,1,Dial(SIP/UserB:PasswordB at SipDeviceNameOnB/${EXTEN},15,tr)

or

exten => _5XXXXX,1,Dial(SIP/UserB:PasswordB at IPAddressOfB/${EXTEN},15,tr)

If you want to avoid putting the password in the dialplan, and make
the authentication process a little more secure, you can also use MD5
authentication.  This page on the wiki explains how:
