Description

Mode

Use this object to control SIP redirection:

  • Accept Redirection – (default) Multiple redirections are allowed.
  • Allow Single Redirect Attempt – Only a single Redirect is allowed per route. Additional Redirects cause crankback to be performed.
  • Reject Redirection – If a Redirect is received, crank back is performed.
  • Stop Hunt – Prevent call attempts on subsequent trunk groups if 3xx is received following an Invite and the SBC fails to establish the call with all the contacts from 3xx.

You must use Stop Hunt with the egress IP Signaling Profile redirect flag Force Requery For Redirection.

Select one of the following to control the processing of contacts received in SIP Redirects:

  • Merge Received Contacts – Contacts received in Redirects are ordered by q-value and inserted at the head of the list of untried contacts.
  • Purge Existing Contacts – Contacts received in Redirects are ordered by q-value and replace untried contacts.
