Configuring Default PANI Contents

Users can configure default contents of the P-Access-Network-Info header in the event of any failure during the NPLI transfer. By default, such failure results in the generation of an empty header. In some circumstances a more informative header may be of benefit to the user.

Default PANI contents can be configured at either the SIP interface level, or at the realm level. If values are configured at both levels, the realm value takes precedence. A value configured at the sip-interface level takes precedence over a default value (empty string) specified at the realm level.

Use the following procedure to configure default PANI contents.

1. Navigate to either the sip-interface or realm configuration mode.

   ACMEPACKET# configure terminal
   ACMEPACKET(configure)# session-router
   ACMEPACKET(session-router)# sip-interface
   ACMEPACKET(sip-interface)#

   or

   ACMEPACKET# configure terminal
   ACMEPACKET(configure)# media-manager
   ACMEPACKET(media-manager)# realm-config
   ACMEPACKET(realm-config)# 

2. Use the select command to specify the target SIP interface or realm.
3. Use the default-location-string parameter to specify the default contents of the P-Access-Network-Info SIP header in the event that NPLI is not available.

   ACMEPACKET(sip-interface)# default-location-sting "Location services temporarily unavailable."
   ACMEPACKET(sip-interface)#

   or

   ACMEPACKET(realm-config)# default-location-sting "Location services not unavailable."
   ACMEPACKET(realm-config)#

4. Use done, exit, and verify-config to complete configuration.

Bear in mind also the default-location-srt-VoWifi parameter if there is an npli-profile assigned to the sip-interface. If configured, this value takes precedence over the default-location-str parameter that may be configured in both the realm-config and sip-interface.
