Managing Signaling

Outbound Destination

Cause Code for Rerouting Calls

Define cause codes that make the Call Dispatcher to retry call routing to an alternative destination. Can be used in environments with multiple SIP and H.323 trunks. Different devices use different cause codes for informing about insufficient line capacity or congestion; list the codes here to accurately recognize rerouting needs. Enter a comma-separated list of string values, for example 34,44,58.

Cause Code for Blocked Calls

Define the cause codes for different trunks that enable the Call Dispatcher to block call routing to the target destination. Codes can be used in environments with multiple SIP and H.323 trunks. Different devices use different cause codes for informing about the line state; list the codes here to accurately recognize a need for temporary blocking. Enter a comma-separated list of string values, such as 48,52.

Delay for Retries

Define how soon Call Dispatcher tries to call a destination that has failed earlier. The default value is 3 minutes. If the value is set to 0, the failed destination is not tried again.

Destination is also reactivated if an inbound call from the destination is detected, or routing information is updated.

Disable Call Routing Between Trunks

Select this option to prevent looping between trunks if more than one trunk participate in call routing. For example, if an external trunk and the Call Dispatcher are configured to pass all unrecognized numbers to each other, this can lead to a never-ending loop if an inbound call to a number not known by either CD or external trunk enters the system.

Handling Unallocated Numbers

Cause code for Unallocated Number

Specify the cause code to be used when an inbound call to a nonexisting number is rejected. See also Rerouting Number for Unallocated Numbers. Enter any integer value; the default value is 1.

Rerouting Number for Unallocated Numbers

Enter the phone number where the inbound calls to numbers not found in the system’s address space are redirected. For example all inbound calls to invalid numbers can be switched to the switchboard queue. If the number is not defined, and no other rerouting is defined, all these non-allocated calls are rejected.

Limit Rerouting to Listed Trunks

Define the trunks, where from calls to nonexisting numbers are routed to a specified Rerouting Number for Unallocated Numbers, other calls are rejected.

Call Identification (CID)

Enable Call Identification

Select this option to enable using call identification (CID) function.

CID-Enabled Destinations

To define the destinations where calls with CID information can be transferred to, enter IP addresses separated with a comma.

CID-Enabled Extensions

To define the extensions where calls with CID information can be transferred to, enter the numbers separated with a comma.

Exceptions in CID-Enabled Extensions

To define the extensions where calls with CID information cannot be transferred to, enter the numbers separated with a comma.

Ringtones

Phone Client Plays Ringtones for Outbound Calls

Define how the terminal component creates ringing tones for outgoing calls. The choices are:

• For internal calls only.

• For all calls.

MRS plays Ringtones to Phone Client for Outbound Calls

Define if Call Dispatcher should manage playing ringtones for plain outbound calls. If the number of plain outbound calls is high, phone client (terminal) can play the tone itself, and thus lessen the MRS load. In that case, remove the selection, and choose For All Calls option in the Phone Client Plays Ringtones for Outbound Calls setting. MRS plays ringtones only for the trunks in the addresses defined in the IP Address for Trunks Requiring Ringing Tone, see the setting below.

IP Address for Trunks Requiring Ringing Tone

Enter IP address of the trunk that require ringing tone from Sinch Contact Center . To enter several trunk addresses, separate them by comma (,).

Advanced Settings

Allow Early Queueing

To enable early queueing, select the checkbox. In addition to this, you must configure a channel, queue or IVR to use early queuing. Added in Sp04.

Exclude Original B Number from Destination Data

To save the modified B number in call log as destination data, select the checkbox. Otherwise original B number is saved.

Use Original Destination In Call Transfers

Define whether CD should use the original destination when transferring a call. The aim is to improve the sound quality by minimizing trunk-to-trunk streams and signalling. The reuse applies only to Least Recently Used (LRU) routes.

Block Hold Signal Sending to Trunk

Select this option to prevent sending the Hold signal to the trunk. SignalHold

Use Session Progress Message

Select this option to make desk phones in system capable of handling 183 Progress Session indications. In this case a call from a SIP phone towards a trunk is not automatically connected when the trunk starts progress stream but the progress indication is used to start streaming towards the desk phone.

Check End Point Address Validity

Select this option to check if the end point IP address is still the same as when it was registered.

Route Video Streams

Select this option to use video ports as well.

Realm for Authenticating SIP End Points

Specify the realm used when authenticating the SIP endpoints in the system. The default value is cssrealm.

Caller Name

Define how the caller name is sent in transfers or outbound calls. Choices are:

• Keep Name

• Remove Name

• Keep Name for Internal Devices

• Remove Name in Transfers

• Use R Number or A Number in Outbound Calls and Transfers

Use CD-Controlled Transfers

Enables using the Call Dispatcher controlled transferring operations instead of the bridge controlled call transfers. The parameter can also be given on bridge-level to target only a single SIP bridge. This parameter is mostly needed in cases where the REFER mechanism is not supported on SIP trunks. Setting is disabled by default, but for SIP bridges it is enabled.

Show Caller and Location

For advanced used only: Useful when both Visible A number and location-based routing is used. Choose one of the options:

• Show Original Caller and Location

• Show Masked Caller but Original Location

Transfer Call Back if Call Rejected

Define, if the call is transferred back if it is rejected.

Max. Waiting Time for IP Phones

Define the time calls are offered to desk phones. If the desk phone rejects the call, or does not answer it in the time defined here, the call is transferred to voicemail, or another secondary address. The default value is 30 seconds.

Add Extra Data to Joined Party

When local calls are joined, possible additional data is passed to application level. To block additional data, remove the selection.

Allocate MRS Modules of Same Priority (Advanced)

Define how MRS modules with the same priority value are allocated for tasks.

• To use all MRS modules in turns, choose Round Robin (the default value).

• To use entire capacity of one MRS first before starting to use another one, choose Static Order.

Use Trunk Reporting

To include routing data of outbound calls in Reporting, choose the appropriate option:

• No Trunk Reporting

• Original B Number Reported

• Modified B Number Reported

• Original And Modified B Number Reported

Ongoing Call Assigns Agent to Location

To assign an agent that is in a call to a location based on the network element used by that call, select the checkbox. The location may define a switching rule, for example add a prefix to the destination number, that causes a specific destination route to be selected. Added in SP04.
