184 Configuration
SIP CTI Dial Plan prefixes
The SIP CTI dial plan prefixes configuration settings are used to prefix
phone numbers sent to the Call Server as a result of SIP CTI call attempts.
Parameter: National Prefix When calls are made to E.164 fully qualified
numbers this parameter is used in combination with the “International Calls
as National” setting in the CTI IP settings section. When a call to an E.164
destination contains the same country code as the local country the call is
placed from the Call Server as a national call using this prefix rather than
the international call prefix.
This parameter is also used to prefix calls that are made with a URI that
contains a phone-context equal to the Public E.164/National domain in the
SIP URI map.
Refer to "Parameter: International Calls As National" (page 183) for an
example of the use of this parameter.
Parameter: International Prefix When calls are made to E.164
fully qualified numbers this parameter is used in combination with the
“International Calls as National” setting in the CTI settings section. If the
“International Calls as National” feature is disabled, all calls to any E.164
number are prefixed with this prefix. If the “International Calls as National”
feature is enabled, only calls to E.164 destinations outside of the local
country are dialed with this prefix.
Refer to the section "Parameter: International Calls As National" (page
183) for an example of the use of this parameter.
Parameter: Location Code Call Prefix This parameter is used to prefix
calls that are made with IRAs with a phone-context equal to the Private/UDP
domain in the SIP URI map.
This parameter is also used in conjunction with the Calling Device URI
Format setting. Refer to the section
"Parameter: Calling Device URI Format"
(page 186) for an example of the use of this parameter.
Parameter: Special Number Prefix This parameter is used to prefix
calls that are made with a URI that contains a phone-context equal to the
Public/E.164 Special Number domain in the SIP URI map.
Parameter: Subscriber Prefix This parameter is used to prefix calls
that are made with a URI that contains a phone-context equal to the Public
E.164/Subscriber domain in the SIP URI map.
