Overview

The SBC Core supports configuring surrogate registration information for a single IP Peer. 

The SBC also supports configuring multiple Address of Records (AORs) for the same IP-PBX using the surrogate registration profile (surrogateRegistrationProfile). Surrogate registration specific statistics are generated separately per surrogate AOR, as applicable, even if the statistics are associated with the same IP Peer. 

When configuring surrogate registration, only one of the following mutually exclusive parameters should be enabled at the IP Peer surrogateRegistration level depending upon the number of AORs per IP Peer desired.

  • Only one AOR per IP Peer for surrogate registration—Configure only userPart at  the surrogate registration level. With this method, you cannot associate a surrRegprofile with this peer.
  • Multiple AORs for IP Peer for surrogate registration—Associate more than one AOR to the same peer by configuring and attaching a surrRegprofile to the IP peer. When using this profile, you cannot configure userPart at the surrogate registration level.

A surrogate registration profile is added, modified and deleted as explained below. For additional feature details, refer to Surrogate Registration Support.

Adding New Profile

  1. Configure a new surrogate registration profile.
  2. Enter various AOR username and corresponding details in this profile.
  3. Attach this profile to given IP Peer (refer Zone - IP Peer - CLI page).
  4. Optionally configure pacing time at IP Peer (refer Signaling - Global - CLI page).
  5. Enable surrogate registration feature at IP Peer.

Modifying Existing Profile

  1. Set AOR state to 'disabled'.
  2. Modify the configuration value of AOR.
  3. Set the AOR state to 'enabled'.

The modified configuration takes effect from the next register onwards for the given AOR.

Deleting Existing Profile

  1. Disable the surrogateRegistration state from IP Peer (see Zone - IP Peer - CLI page).
  2. Detach the profile from ipPeer.
  3. Remove the profile.

As soon as the administrator detaches the profile from ipPeer, all AORs in the profile are queued for De-registration. If profile is re-attached, a fresh registration request is queued. Note that the register will happen after all of the de-register requests resulting from detachment of the profile are executed. 


Surrogate Registration Profile Limitations

  • Configuration limitations: 
    • Up to 200 subscribers for each AoR
    • Up to 1,000 surrogate registration profiles system-wide
    • Up to 256,000 AoRs for surrogate registration system-wide and 64,000 for AoRs in the SBC SWe: 

      • The maximum number on the SBC 7000 and SBC 5400 platforms is 256,000. (1,000 Surrogate Registration profiles, each supporting 256 surrogate AORs).

      • The maximum number on the SBC SWe platform is 64,000 per SCM instance, up to 256,000.

  • Subscriber numbers must be unique across the system.
  • Configure subscriber numbers using the same format as expected from the received call.
  • The SBC supports a registration rate of 100 registrations/second.


Refer to SBC Provisioning Limits for details regarding limitations.

Note

If the same AorUsername is configured on two different peers, AorUserName start and end range values for either peer should not fall within start and end range values of the other peer. 

Note
Do not attach a surrogate registration profile to more than one peer.
  


Command Syntax

The CLI syntax to configure the Surrogate Registration Profile is shown below:

% set profiles services surrogateRegistrationProfile <profile name> aorUserName <user name> 
	aorAuthPassword <6-32 characters>
	aorAuthUserName <1-127 characters>
	aorSendCredentials <challengeForAnyMessage | challengeForAnyMessageAndInDialogRequests | challengeForRegister>
	aorState <disabled | enabled>
	subscriberNumbers <subscriber numbers list>
	userEndRange <1-32>
	userStartRange <1-32>

Command Parameters

SIP Resource Priority Header Profile Parameters

ParameterLength/RangeDescription
surrogateRegistrationProfile
1-23 characters<profile name> – Surrogate registration profile name.
aorUserName1-127 characters<AOR user name> – Surrogate AOR user name.

aorAuthPassword

6 to 32 characters

<password> – The authorization Password for surrogate registration.

Note: While exporting the configuration, the plain text authentication password for aorAuthPassword is replaced with “SonusDefaultValue” in the config dump. When you import the same config dump (xml), configure the entity with the appropriate value. Otherwise, it will still have the value “SonusDefaultValue”.

aorAuthUserName

1-127 characters<auth user name> – The authorization User Name for surrogate registration.

aorSendCredentials

N/A

Use this parameter to define how the credentials are sent. The options are:

  •  challengeForAnyMessage – The SBC sends credentials for REGISTER, INVITE, PRACK, UPDATE, REINVITE and BYE when these messages are challenged.

  • challengeForAnyMessageAndInDialogRequests – The SBC sends credentials for REGISTER, INVITE, PRACK, UPDATE, REINVITE and BYE when these messages are challenged. The SBC also sends credentials by default as per last challenge in the in-dialog requests such as PRACK, UPDATE, REINVITE and BYE when any one of these methods is challenged earlier in the call.

  • challengeForRegister (default) – The SBC sends credentials only for REGISTER when challenged. Challenges for any other messages are returned to the IP-PBX.

aorState

N/A

Enable or disable the specified Surrogate Registration profile.

  • disabled (default)
  • enabled
subscriberNumbers32 characters per number
(including country code and prefix)

<subscriber numbers list> (default = <Null>) – Enter up to 200 individual space-separated subscriber numbers for this AoR. Allowed characters: - _ ( ) * . + $ ? / % = ! , ‘  ~ & a-z A-Z 0-9

NOTE: Subscriber numbers must be unique across the system.

NOTE: Configure subscriber numbers using the same format as the numbers expected from the received call.

userEndRange

1-32<end number> – Use this attribute to specify the Ending number in the range of user numbers in this surrogate registration profile.

userStartRange

1-32<starting number> – Use this attribute to specify the Starting number in the range of user numbers in this surrogate registration profile.
