Trunk Provisioning - Egress IP Attributes SIP Headers And Parameters


Egress IP Attributes SIP Headers and Parameters

Parameter

Description

Include Charge InformationSelect the includePChargeInfo option to map charge information in a call setup message (i.e., the charge number parameter of an IAM) to egress P-Charge-Info header in INVITE message. If the ERE returns billing information in a policy response, the SBC ensures that the egress P-Charge-Info header in INVITE message is populated with the indicated data. If the SBC receives a SIP INVITE message for a call destined to the PSTN, the SBC populates the charge number parameter of the outgoing IAM based on the egress P-Charge-Info header in INVITE message.
  • Include None (default)
  • Include PCharge Info
SIP{ To Header MappingThis parameter indicates which number is mapped and returned in the outgoing SIP To header. Options include:
  • Called Number – TO header is mapped using the called number.
  • Gap Dialed Number – TO header is mapped using the Generic Address Parameter from mime, if applicable.
  • None (default) – The TO header user part is mapped from the Original Called Number, if present. Otherwise, it is mapped from the Called Number. The Original Called Number may be taken from the Diversion or the History-Info header, if present, in a SIP Invite.
  • Original Called Number Ocn – TO header is mapped using the redirecting original Called number OCN parameter. This is filled from the SIP Invite using the Diversion or the History-Info header, if present.
Destination Trunk Group OptionsUse this parameter to specify destination trunk group options.
  • Include Dtg – Include the destination trunk group parameter in SIP headers sent over associated trunk group.
  • Include None (default) – Do not include any trunk group information.
  • Include Tgrp With Domain Name – Include trunk group with domain name.
  • Include Tgrp With Ip Address – Include the destination trunk group, and include the trunk context as domain name.
Originating Trunk Group OptionsUse this parameter to specify originating trunk group options.
  • Include None – (default) Do not include any trunk group information.
  • Include Otg – Include the originating trunk group parameter in SIP headers sent over the associated trunk group.
  • Include Tgrp With Domain Name – Include the originating trunk group, and include the trunk context as domain name.
  • Include Tgrp With Ip Address – Include the originating trunk group, and include the trunk context as IP address.
Generate Call ID UsingUse this parameter to determine how ingress Call-ID generates the egress Call-ID.
  • Do Not Use Ingress Call ID – Generates egress Call-id independent of ingress Call-ID.
  • Use Ingress Call ID By Adding Static String – Generates egress Call-id using ingress Call-ID and a static string (Egress Call-ID Static String) configured in the SIP trunk group.
    Egress Call-id is the aggregate of ingress Call-ID and static string.
  • Use Ingress Call ID By Prepending – Generates egress Call-ID using ingress Call-id and locally generated string. Egress Call-ID is the aggregate of ingress Call-ID and locally generated string.
Session Expires Refresher

Controls whether the refresher parameter is sent in the Session-Expires header and is enabled when the Customized Session Timer Behavior flag is selected. Options include:

  • Not Send (default) – The Session-Expires refresher parameter is not sent in the initial outgoing INVITE message, re-INVITE message, and UPDATE message.
  • Uac – When selected, the parameter refresher uac (User-Agent Client) is sent in the Session-Expires header.
  • Uas – When selected, the parameter refresher uas (User-Agent Server) is sent in the Session-Expires header.
