The

Unable to show "metadata-from": No such page "_space_variables"
acting as P-CSCF transparently passes the P-Called-Party-ID header towards UE when pCalledPartyIdHeader transparency flag is enabled.

If the dialog initiating or out-of-dialog request contains "P-Called-Party-ID" header, SBC stores the value of this header before forwarding the request to the next hop. If the corresponding response contains P-Preferred-Identity or P-P-Preferred-IdentityAsserted-Identity header, SBC removes these headers and inserts a P-Asserted-Identity header containing the stored value of P-Called-Party-ID header.

The

Unable to show "metadata-from": No such page "_space_variables"
adds P-Asserted-Identity header in 1xx or 2xx response received from UE before forwarding the response to IMS CN. The P-Asserted-Identity is set to the saved P-Called-Party-ID header while sending the request message towards UE.

If P-Called-Party-ID header does not have Display Name, the associated URI’s display name stored at the time of registration is used (received in P-Associated-URI header in 200 OK to REGISTER).

The

removes P-Preferred-Identity or P-Asserted-Identity header field, if present in the ingress SIP response message from UE.

The

Unable to show "metadata-from": No such page "_space_variables"
acting as IBCF exhibits following behavior:

  • Transparently passes the P-Called-Party-ID header if received from ingress call-leg to egress call-leg (configurable).
  • Deletes the P-Called-Party-ID header if received from ingress call-leg to egress call-leg (configurable).
  • Transparently passes the P-Asserted-Identity header (including Display Name) if received in a SIP response message while sending response from ingress call-leg to egress call-leg (configurable).
  • Deletes the P-Asserted-Identity header if received in a SIP response message while sending response from ingress call-leg to egress call-leg (configurable).

The CLI syntax to enable/disable and transparently pass P-Called-Party-ID header is shown below.

% set profiles signaling ipSignalingProfile <Profile Name> commonIpAttributes flags pCalledPartyIDSupport <disable | enable>
% set profiles signaling ipSignalingProfile <SIGNALING_PROFILE_NAME> commonIpAttributes transparencyFlags pCalledPartyIdHeader <enable | disable> 

See IP Signaling Profile - CLI for details of this command.
