In this section:
This section describes CLI syntax and parameters for the SIP trunk group 'callRouting' object.
Use this object to configure the method to route a call or request to the next-hop entity for this SIP trunk group.
When configuring the SBC for DTG routing, trunk group names must use all UPPERCASE letters.
Command Syntax

Command Parameters
Zone SIP Trunk Group Parameters
Parameter | Length/Range | Description |
---|---|---|
addStoredPathAsTopRoute | N/A | When enabled, adds the stored Path header as the topmost Route header (on top of stored Service-Route headers) in the outgoing out-of-dialog requests when useRouteSet is set to "stored ".
|
ansSupervisionTimeout | 0-1000 | Configure this parameter on the ingress trunk group specifying the timeout period (in seconds) for the egress trunk group to receive the first backwards message from the called party exchange (SIP 180 - “Ringing" and SIP 183 - “Progress") until the call is answered. If the timeout period expires, the answer supervision action specified is triggered. A value of "0" disables this timer (default = 300). |
ansSupervisionTimeoutAction | N/A | Action to take if the answer supervision timer expires.
|
crankbackProfile | N/A | Use this option to specify a crankback profile to apply to the trunk group. Crankback profiles can be assigned at three levels: trunk group, zone, and global. By default, a trunk group does not have a crankback profile assigned. If no profile is specified, a trunk group inherits the crankback profile from its zone. If a zone has no crankback profile specified, it inherits the crankback profile assigned at the global level. |
dnsCrankback | N/A | Enable this flag to apply a DNS crankback profile for the received SIP error response.
NOTE: dnsCrankback must be enabled on an egress SIP trunk group. The crankback profile assigned to the egress trunk group is used for DNS crankback. |
internationalNoaPlus | N/A | Enable flag to set CPN and CIN NOA to “International” when number begins with '+'.
|
sendRouteUriToPsx | N/A | Use this flag to control the sending of Route-URI to PSX.
NOTE: This flag works in conjunction with "Perform Route Header based Routing" flag configured from PSX Feature Control Profile screen. Refer to PSX Documentation for details. |
useRouteSet | N/A | This parameter determines the routeset used when routing a call.
NOTE: Attributes Refer to IMS Routing for Route Header and Roaming User for additional details. |
The SBC maps the received SIP response from the egress call leg using the sipToCpcCauseMapProfile from the egress sipTrunkGroup. The CPC cause is then looked up in the egress sipTrunkGroup's crankbackProfile.
- If a match is found, the SBC attempts a new target.
- If a match is not found, SBC skips the DNS crankback and proceeds with the normal crankback at CC level using the ingress sipTrunkGroup's crankback profile
