The domain name and the port number will be used in configuring the device list on managing site.
Dialing prefix of inter-site calling is dialed before the extension number of the remote site. For
example, #1-11-200#, in which 1 is the prefix, 11 is the site id of the called party, and 200 is the
extension of the called party.

dialing #2-8005551212# the call to 8005551212 will be routed to PSTN through a trunk selected by
the managing site.
