platform supports processing the Resource-Priority Header (RPH) to classify a call as an emergency call. If the namespace and r-priority of a received r-value in the initial INVITE RPH exactly matches with the namespace and r-priority respectively of a configured value, then the call is considered an emergency call. The comparison is case-insensitive, and multiple r-values can be processed in incoming INVITE.

The SBC can use the IPSP transparency flag 'resourcePriorityOptionTag' to transparently pass the 'resource-priority' option tag received in Require or Supported header of various SIP messages, such as INVITE, REGISTER, SUBSCRIBE (but not in-dialog SUBSCRIBE), PUBLISH, REFER, NOTIFY, UPDATE, MESSAGE, OPTIONS, CANCEL, and GW-GW transparency. This flag is available to both the ERE and external PSX. See commonIpAttributes (SIP) for Refer to Common IP Attributes - SIP - CLI for CLI details.
