NPLI Emergency Call Configuration

Use this procedure to buffer emergency INVITES pending the receipt of NPLI from the PCRF. This procedure is required for users subject to German telecommunications regulations. For other users, the procedure is optional.

1. Navigate to sip-config configuration mode.

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

2. hold-emergency-calls-for-loc-info—Use this parameter to both enable the buffering of emergency INVITES (thus complying with German regulations), and to specify the time (in seconds) that INVITES are buffered.
   By default hold-emergency-calls-for-loc-info is set to the value 0, which disables the buffering of emergency INVITEs.
   Set hold-emergency-calls-for-loc-info to a non-zero value, within the boundaries acceptable to the German regulator, to enable the timer.

   ACMEPACKET(sip-config)# hold-emergency-calls-for-loc-info 5
   ACMEPACKET(sip-config)#

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