When a dialed number matches a short code that specifies that the number should be dialled, there are two methods by which the routing of the outgoing call can be controlled.
Routing Calls Directly to a Line
Every line and channel has an Outgoing Group ID setting. Several lines and channels can have belong to the same Outgoing Group ID. Within short codes that should be routed via a line within that group, the required Outgoing Group ID is specified in the short code's Line Group ID setting.
Routing Calls via ARS
The short code for a number can specify an ARS form as the destination. The final routing of the call is then controlled by the setting available within that ARS form.
ARS Features
Feature
Description
Secondary Dial Tone
The first ARS form to which a call is routed can specify whether the caller should receive secondary dial tone.
Out of Service Routing
ARS forms can be taken out of service, rerouting any calls to an alternate ARS form while out of service. This can be done through the configuration or using short codes.
Out of Hours Routing
ARS forms can reroute calls to an alternate ARS form outside the hours defined by an associated time profile.
Priority Routing
Alternate routes can be made available to users with sufficient priority if the initial routes specified in an ARS form are not available. For users with insufficient priority, a delay is applied before the alternate routes become available.
Line Types
ARS can be used with all line types.
A SIP line is treated as busy and can follow alternate routes based on the SIP line setting Call Initiation Timeout. Previously a SIP line was only seen as busy if all the configured channels were in use.
IP lines use the NoUser Source Number setting H.323SetupTimerNoLCR to determine how long to wait for successful connection before treating the line as busy and following ARS alternate routing. This is set through the IP line option Call Initiation Timeout.
Multi-Site Network Calls
Calls to multi-site extension numbers are always routed using the appropriate network trunk. ARS can be configured for multi-site network numbers but will only be used if the network call fails due to congestion or network failure.
Main Route
The ARS form 50, named "Main" cannot be deleted. For defaulted systems it is used as a default route for outgoing calls.
Routing Calls to ARS
Create the ARS form.
Create the required system, user or user rights short code to match the user dialing.
In the Telephone Number field, define the digits that will be used to match a short code in the ARS form.
Use the Line Group ID field drop-down to select the ARS form required for routing the call.
