    If (the other phone is also registered on same asterisk)
                  You just have to Dial(SIP/${EXTEN})
                   You need a trunk, or route the call to that
equipment(VoIP server) where the other phone(s) is/are registered so that
you can bridge both channels. Here you have to Dial(SIP/${EXTEN}@Trunk-IP)
or you can create a trunk in sip.conf to route call out, and the receiving
side should then route the call to the destination phone.
