3- Create the new Domain:
+
* Enter a '''name''' for the NAP
−
 
+
−
* Enter a configuration '''Name''' for this domain.
+
−
* Enter a '''Domain Name''' for the SIP Registration Domain (domain can be a FQDN or an IP address)
+
−
* Set the number '''Maximum Registered Users''' for this domain
+
−
* Set the Expires value used by SBC when the remote device doesn't supply one ('''Default Contact Expire''')
+
−
* Select '''Routing Method''' the system will use to route calls to registered users (if enabled in routing scripts).
+
−
** '''Register source''': Sends SIP Invite to the registering source IP address.
+
−
** '''Contact''': Sends SIP Invite to the 'contact' from the Register message.
+
−
* Set the '''Default Contact Expiration''', this value will be used when no ''Expires'' value is supplied by the user agent.
+
−
* 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.
+
−
* Set the '''Maximum Contact Expiration''', this is the maximum ''Expires'' value that can be supplied by a user agent. Higher value are replaced by this parameter.
+
−
* 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.

A regular NAP is a NAP with specific Proxy address (either IP address or FQDN from 3.1 onward). Configuring SIP Registration for regular NAP requires no extra step from using steps for configuring a regular NAP. A NAP that accepting SIP registration must be a Registrar. Registrar accepts SIP registration request from ProSBC after ProSBC receiving this request from remote SIP end point whom it wants to register to this registrar. You must configure SIP Registration Domain(s) for your regular NAP and associate them to this regular NAP (Registrar).

To create a new NAP:

1- Click NAPs in the navigation panel

2- Click Create New NAP

3- Create the new NAP:

  • Enter a name for the NAP
  • Click Create

4- Verify that the NAP was successfully created message appears

5- Associate a SIP transport server with the new NAP:

  • Select a SIP Transport Server from the Available list
  • Click "<<" to associate the LAN_SIP_TS with the NAP

6- Enter SIP Server proxy address:

7- Associate a Port range with the new NAP:

  • Select a port range from the Available list
  • Click "<<" to associate LAN_Vlan:0 Port range with the NAP

8- Associate a SIP Domain with the new NAP. If you have more then 1 registrar domain using the same registrar you can associate all of them with the NAP:

  • Select a sip domain from the Available list
  • Click "<<" to associate the SIP Domain with the NAP

9- Configure settings for the following parameter groups as required:

  • Registration Parameters
  • Authentication Parameters
  • Network Address Translation
  • SIP-I Parameters
  • Advanced Parameters
  • Click Save
