The

supports sending authenticated INVITE with same call ID as an INVITE challenged with 401 (Unauthorized) or 407 (Proxy Authentication Required) response using the "Same Call Id for Required Authorization" flag which is set in Egress IP Attributes for IP Signaling Profile. This flag is only available to configure when both of the following flags are enabled:

  • "Status Code 4xx-6xx" relay flag
  • "Authcode Headers" transparency flag

This feature is supported via both PSX and ERE routing using the configuration settings described below.

PSX Routing

From the PSX IP Signaling Profile associated with the trunk group, set the following flags:

  1. Enable "AuthCode Headers" flag in the transparency section.
  2. Enable "Status code 4xx-6xx" relay flag.
  3. Enable "Same Call Id for Required Authorization" egress flag.
    1. Under SIP headers and parameters, set "Generate Call-ID Using" to "Do not use ingress call-id".

ERE Routing

From the SBC IP Signaling Profile associated with the trunk group, set the following flags:

  1. Enable "AuthCode Headers" transparency flag.
  2. Enable "Status Code4xx6xx" relay flag.
  3. Enable "Same call Id for Required Authorization" egress flag.

The default behavior of the
