Note

Native Call Forking does not support GW-GW scenarios.

Use the AoR Group profile object to group together sets of Address of Record (AoR) values to be used in Application Layer call forking. With this feature, the SBC receives a single initial INVITE for a target and creates multiple initial INVITEs with different call-Ids to different targets. These additional targets are associated with the received target through configuration. An AoR Group Profile is associated with a VOIP Subscriber profile. When the VOIP Subscriber is the target of a call, the contents of the AoR Group Profile are used in forking calls to multiple subscriber devices (AoRs).

Refer to Profiles - Voip Subscriber and Configuring Call Forking Feature in the SBC for more information.

To View AoR Group Profiles 

On the SBC main screen navigate to All > Profiles > Aor Group Profile

The Aor Group Profile window opens showing a list of any configured AoR Group Profiles.

The parameters and their descriptions are given below:

Table 1: Parameters

ParameterLength/RangeDescription
NameUp to 23 charactersSpecifies the name to assign to the profile.
Aor Data ListUp to 1500 characters

Specifies up to 10 AoRs for call forking.

You have the option to include two timer values within an AoR:

The delayBeforeRingTimer (default: 0) - Specifies a duration in milliseconds (0 to 300000) to delay forking to the destination. If not provisioned or zero, the SBC does not delay forking to the destination.  This is applied per AoR. A forking call to this AoR is initiated only if final (2xx or 3xx) response is not received from any other AoR until the specified time. It is applied separately if there are multiple forked calls for the same AoR.

The answerTooSoonTimer (default 0) - Specifies a duration in milliseconds (0 to 300000) used by the SBC to terminate a call if it receives an answer before the specified time. This is applied per AoR. A final answer received before the specified time causes the call to be terminated with BYE. Other forked calls to other AoRs stay intact. It is applied separately if there are multiple forked calls for the same AoR.

You must begin the AoR entry with a URI type. The basic syntax for specifying an AoR:

<urischeme>:<user>@<domain>;<delayBeforeRingTimer>;<answerTooSoonTimer>;user=phone

Inclusion of the timer values is optional, but if included, the order and syntax must be maintained such as in the following examples of valid AoRs:

  • sip:bob@example.com;10000;2000;user=phone
  • sip:bob@example.com;0;2000
  • sip:bob@example.com
  • sip:bob@example.com;0;0;user=phone

Separate complete AoRs with a comma and do not include spaces.

Note:  For standard routing cases, the "user=phone" parameter is used.

Preferred IdentityUp to 1500 characters

Specifies the preferred identity for the AoR group.

Aor Dialog Attributen/a

Specifies the user part that is used for the active early dialog selection behavior.

The options are:

  • useFirst18x (default)
  • useLast18x
Wait for Answer0 to 300000 milliseconds

Specifies a single time period value in milliseconds for all AoRs to which the ingress call is forked. Any non-2xx final answer (3xx responses) is delayed until the configured time expires, as follows:

  • ACK is generated but corresponding INVITE is not sent to egress.
  • If a 2xx response is received before timer expires, INVITE is not generated for 3xx.

The default value is 0.

Note: Currently, the timer should only be configured up to 120 seconds.

Make the necessary entries and click Save.
