* Set the '''Minimum Contact Expiration''', this is the minimum ''Expires'' value that can be supplied by a user agent. Lower values will be rejected with a 423 'Interval too brief' response.

* Forwarding Parameters:
 
−
** Select the Registration '''Forwarding Mode''' to the registrar:
 
−
*** '''Contact Remapping''': Changes the user and the IP address.
 
−
*** '''Contact Passthrough''': Doesn't change anything. Enables devices to be contacted directly without going through the SBC.
 
−
** Set '''Minimum Registrar Expiration''', this is the minimum ''Expires'' value sent by the SBC to the registrar.  If a user agent 'Expires' value is greater than this parameter, the SBC will do rate adaptation between the user agent and the Registrar.
 
−
** Set '''Maximum Pending Register Forward''', the maximum number of simultaneous pending register requests allowed for this domain.  New REGISTER request are being refused passed this threshold.
 
−
** Set '''Maximum Simultaneous Register Forward''', the  maximum number of simultaneous active register requests allowed for this domain. New REGISTER request are being refused passed this threshold.
 
−
** Select the Registration '''Registrar Selection Mode''' to the registrar:
 
−
*** '''Active/Standby''': The active registrar is the one with status up and the lowest priority (automatic fallback).
 
−
** Enable the '''Forward After Switchover''': After a switchover, the first register refresh request from each user will be forwarded to the active registrar.

Configuring SIP Registration for Open NAP in ProSBC requires no extra step from using steps in configuring an Open NAP.
