Interactions for Multifrequency Signaling

Last Updated : Oct 30, 2012 |

This section provides information about how the Multifrequency Signaling feature interacts with other features on the system. Use this information to ensure that you receive the maximum benefits of Multifrequency Signaling in any feature configuration.

ASAI

ANI collected from incoming R2-MFC signaling can be used with ASAI.

Abbreviated Dialing

Although calls dialed automatically from an abbreviated dialing privileged list complete without COR checking, ANI prefix and ANI truncation still apply.

Attendant Console

If the attendant assists or extends a call for a station using Straightforward Outward Completion and Through Dialing, and if the attendant has not yet released the call when the request for ANI comes in from the far end, the attendant’s COR is used to select the ANI for the call. If the attendant has already released the call when the request for ANI comes in from the far end, the attendant’s COR is used to select the ANI for the call.

Authorization Codes

The COR of the authorization code as administered on the authorization-code screen is not used for ANI prefix determination, even if the originating endpoint enters an authorization code before call processing for an outgoing call seizes an outgoing trunk. If the originating endpoint is an extension, the extension’s ANI is used. If the originating endpoint is an incoming trunk, the ANI for PBX is used.

Bridging

The ANI of a telephone’s primary extension also applies to calls originated from a bridged call appearance of that extension on another terminal. ANI prefix and ANI truncation applies to the primary extension number of bridged call appearances.

Call Detail Recording (CDR)

CDR records ANI collected from incoming MF signaling.

For India MFC, on incoming calls, ANI digits may be appended with zeroes if the actual ANI digits are less than the administered ANI-length. In these calls, CDR displays the zero digits.

Call Redirection

A call is redirected if any of the following are active: Call Forwarding, Call Coverage, Send All Calls, or Night Service.

Call Vectoring

Call Vectoring can now use ANI collected from incoming MFC signaling.

The ANI of a call vector is not used when a call vectoring route-to command routes a call over an outgoing trunk. Instead, the ANI of the originating party is sent.

DID No Answer Timer

DID No Answer Timer is applied to MF signaling DID calls.

Distributed Communications System (DCS)

In a DCS arrangement, the ANI sent to the CO is determined by the ANI for PBX on PBX_B, but the category sent to the CO is determined by the Category for MF ANI field on the Class of Restriction screen for the incoming DCS trunk or by the type of call.

Expert Agent Select (EAS)

For ANI, the EAS agent’s login extension number and COR overrides the extension number and COR of the physical terminal where the agent is logged in. ANI prefix and ANI truncation apply to logged in EAS agents.

Hunt Groups and Automatic Call Distribution (ACD) Splits

For ANI, a physical terminal’s extension number and COR overrides the extension number and COR of the hunt group or ACD split that is a member of or logged into. ANI prefix and ANI truncation apply to terminals that are members of hunt groups or logged into ACD splits.

Intercept treatment

For DID MF signaling calls that are denied, you can administer whether the corresponding B.x signal or intercept tone should be sent to the CO. The default is to send the administered DID/TIE/ISDN Intercept Treatment. If the option to send the B.x signal is set, then:

  • For Group II calls, the B.x signal for the intercept is sent to the CO.

  • For non-Group II calls, if the CO dials an invalid number, the trunk is locked (regardless of this option). If the CO dials a number that is valid but unassigned, intercept tone is sent to the CO.

Multimedia Call Handling (MMCH)

For call origination, multimedia complexes use the COR assigned to their telephones. ANI prefix and ANI truncation will apply to the telephones assigned to multimedia complexes.

Off-Net Call Coverage or Call Forwarding

If the originating endpoint is an extension, the extension’s ANI is used. If the originating endpoint is an incoming trunk that can supply ANI, the ANI received from the incoming trunk is used. If the originating endpoint is neither of the above, the ANI for PBX is used.

Personal Station Access (PSA)

For ANI, the PSA extension number and COR overrides the extension number and COR of the physical terminal where the PSA extension number is associated. ANI prefix and ANI truncation will apply to associated PSA extension numbers.

Remote Access

The COR of a remote access barrier code is not used for ANI prefix determination when the originating end point dials a remote access extension and then places a call. If the originating endpoint is an extension, the extension’s ANI is used. If the originating endpoint is an incoming trunk, the ANI for PBX is used.

Station Set Displays

When no ANI is possible, if station sets are equipped with display option, they do not display the ANI digits. Instead, the trunk group name displays. When ANI is possible, ANI displays on the station set.

Note:

For India Only. If ANI digits are padded with zero, then zeroes also are displayed along with ANI digits.

Tandem/Offnet Calls

If ANI digits are received on incoming MFC calls, the ANI digits are sent to outgoing tandem/off-net calls.

Note:

For Russia Only. The ANI is requested on incoming trunks only when all the address digits have been collected. When the incoming trunk on a tandem call is a Russian incoming local trunk administered to collect ANI, the server collects all ANI digits before seizing the outgoing tandem trunk. This happens even if ARS is administered with a min value low enough that it would be possible to determine an outgoing route through digit analysis.

Note:

For India Only. On an outgoing tandem-call, the default operation is to send the ANI-Not-Available forward signal if ANI is unavailable from the incoming trunk. However, to support this operation, leave the ANI for PBX field blank, and define the ANI-Not-Available signal.
