Applies to version(s): v3.0

A SIP domain represents a grouping of devices (or users) that can communicate with one another. You must configure SIP Registration Domain for your system. The first step in doing so is to create a SIP Domain:


1- Click SIP Domain in the navigation panel

2- Click Create New Domain

3- Create the new Domain:

  • Enter a configuration Name for this domain.
  • Enter a Domain Name for the SIP Registration Domain (domain can be a FQDN or an IP address)
  • Set the number Maximum Registered Users for this domain
  • Set the Expires value used by SBC when the remote device doesn't supply one (Default Contact Expire)
  • Select Routing Method the system will use to route calls to registered users (if enabled in routing scripts).
    • Register source: Sends SIP Invite to the registering source IP address.
    • Contact: Sends SIP Invite to the 'contact' from the Register message.
  • Set the Default Contact Expiration, this value will be used when no Expires value is supplied by the user agent.
  • Set the Minimum Contact Expiration, this is the minimum Expires value that can be supplied by a user agent. Lower values will be rejected with a 423 'Interval too brief' response.
  • Set the Maximum Contact Expiration, this is the maximum Expires value that can be supplied by a user agent. Higher value are replaced by this parameter.
  • Forwarding Parameters:
    • Select the Registration Forwarding Mode to the registrar:
      • Contact Remapping: Changes the user and the IP address.
      • Contact Passthrough: Doesn't change anything. Enables devices to be contacted directly without going through the SBC.
    • Set Minimum Registrar Expiration, this is the minimum Expires value sent by the SBC to the registrar. If a user agent 'Expires' value is greater than this parameter, the SBC will do rate adaptation between the user agent and the Registrar.
    • Set Maximum Pending Register Forward, the maximum number of simultaneous pending register requests allowed for this domain. New REGISTER request are being refused passed this threshold.
    • Set Maximum Simultaneous Register Forward, the maximum number of simultaneous active register requests allowed for this domain. New REGISTER request are being refused passed this threshold.
    • Select the Registration Registrar Selection Mode to the registrar:
      • Active/Standby: The active registrar is the one with status up and the lowest priority (automatic fallback).
    • Enable the Forward After Switchover: After a switchover, the first register refresh request from each user will be forwarded to the active registrar.
  • Click Create
