Trunk Group Call Routing Parameters:
Parameter | Description |
---|---|
Use Route Set | This parameter controls the routeset usage when routing a call.
Note: The attributes Rcb Next Hop And Stored and Roaming Or Stored are not supported on ERE and are intended for use with an external PSX only. |
Ans Supervision Timeout | 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). |
Ans Supervision Timeout Action | Specifies the action to take if the answer supervision timer expires.
|
Crank Back Profile | Select the name of the crankback profile to use for the selected trunk group. By default, no profile is selected and the trunk group inherits the profile from the zone level. Refer to Call Crankback Profile for more information. |
International Noa Plus | Enable this flag to set CPN and CIN NOA to “International” when number begins with '+'.
|
Add Stored Path As Top Route | When enabled, this flag 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 Use Route Set is set to stored.
|
DNS Crankback | This parameter defines whether to apply DNS crankback profile or not for received SIP error response. If it is enabled, DNS crankback feature is applied.
