are the same. You will also be given and password. These three parameters are used to authenticate your
telephone lines.
Proxy Server is a “Go-Between” that makes requests on behalf of other clients. Its primary roll is a route
packets the fastest way possible and enforced routing policies, even if it has to rewrite specifi c parts of the
request before forwarding the packet.
Register Server sends a Registrar Server requests so that it will place vital information in a location for the
Domain Server. Some SIP IP Trunk providers require that a Registrar Sever be reference in order to keep the
connection working correctly.

Direct Inward Dialing
One feature that some SIP Telephone Line providers offer is the ability to use Direct Inward Dial (DID)
numbers, often called “Private Lines”. DID numbers are generally published direct telephone numbers that
rings directly to a specifi c user’s extension, bypassing the attendant and auto attendant. DIDs were once
reserved for large companies who could buy hundreds of sequential telephone numbers, which were assigned
to specifi c employees. SIP Telephone Line providers can now allow smaller companies to purchase a smaller
quantity of numbers, even as few as one. However, not all SIP Telephone Line providers offer the DID feature
so it is important to check before signing any contacts.
Note:
SIP Telephone Lines with DID assignments are not affected by the Answering Position
assignment, found under Voice --> Trunk --> Answering Position.
When entering a new DID, make sure that the “Trunk Group” in the DID Table is set to all or
matches the hunt group on the “Trunk Group” page.
Depending on your SIP IP Trunk provider and the
X -25 system programming may restrict what Outgoing Caller
ID can be sent. Ideally, if your DID rings directly to an extension, you can defi ne the Outgoing Caller ID as the
same number. If left blank, your companies main telephone number should be sent.
