Command Parameters

Caption

0	Table
1	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`". `disabled` (default) `enabled`
`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. `release` (default) `trapAndRestart`
`crankbackProfile`	N/A	Crankback profile name. NOTE: The crankbackProfile assigned to the egresstrunkGroup is used for DNS crankback,T
`dnsCrankback`	N/A	Enable flag to apply DNS crankback profile for the received SIP error response. `disabled` (default) `enabled` NOTE: dnsCrankback must be enabled on the egress sipTrunkGroup.
`internationalNoaPlus`	N/A	Enable flag to set CPN and CIN NOA to “International” when number begins with '+'. `disabled` (default) `enabled`
`sendRouteUriToPsx`	N/A	Use this flag to control the sending of Route-URI to PSX. `disabled` (default) – Route-URI is not sent to PSX. `enabled` – Route-URI is sent to PSX NOTE: This flag works in conjunction with "Perform Route Header based Routing" flag configured from PSX Feature Control Profile screen.

useRouteSet

N/A

This parameter determines the routeset used when routing a call.

disabled (default) – Request is routed using routing database.
rcbNextHopAndStored – Request from a registered subscriber is routed to the same next hop (registrar IP stored in registration), and the stored Service Route is copied to egress.
received – Request is routed using the received routeset in the request.
roamingOrStored – If the UE is in roaming mode, request is routed based on Destination Trunk Group (DTG) loopback where DTG is the route obtained during REGISTRATION. If UE is not in roaming, the request is routed in same manner as stored option.
stored – Request is routed using Path or Service-Route stored during registration.
storedAll – All requests (including refresh registers) are routed using Path or Service-Route stored during registration.

NOTE: Attributes rcbNextHopAndStored and roamingOrStored are not supported on ERE and are intended for use only with an external PSX.

Refer to IMS Routing for Route Header and Roaming User for additional details.

Info

title	Note on Crankback

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
