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.
