/mcpInteraction Feature You can use speed dial to reach destinations that require a FAC, CMC, dialing pauses, or additional digits (such as a user extension, a meeting access code, or a voicemail password). When the user presses the configured speed dial, the phone establishes the call to the destination number and sends the specified FAC, CMC, and additional digits with dialing pauses inserted. Speed Dial and Abbreviated Speed Dial ClientMatterCodesandForcedAuthorizationCodesRestrictions Table 56: Client Matter Codes and Forced Authorization Codes Restrictions Description Restriction H.323 analog gateways do not support CMCs or FACs because these gateways cannot play tones. Analog gateways Calls that are forwarded to a CMC- or FAC-enabled route pattern fail because no user is present to enter the code. When a user presses the CFwdALL softkey and enters a number that has CMC or FAC enabled on the route pattern, call forwarding fails. To minimize call-processing interruptions, test the number before you configure call forwarding. To do this, dial the intended forwarding number; if you are prompted for a code, do not configure call forwarding for that number. Advise users of this practice to reduce the number of complaints that result from forwarded calls that do not reach the intended destination. Call forwarding Calls that originate from a SIP trunk, H.323 gateway, or MGCP gateway fail if they encounter a route pattern that requires CMCs or FACs and the caller is not configured with Cisco Unified Mobility. Cisco Unified Mobility The CMC and FAC feature on Cisco Mobility does not support an alternative number as its dial via office (DVO) callback number. The DVO callback number must be the number that is registered on the Mobility Identity window. Dial via Office callback number CMCs and FACs do not work with failover calls. Failover calls After dialing the phone number, hearing-impaired users should wait one or two seconds before entering the authorization or client matter code. Hearing-impaired users Cisco does not localize CMCs or FACs. The CMC and FAC features use the same default tone for any locale that is supported with Cisco Unified Communications Manager. Note For Cisco Mobility, CMCs and FACs are localized.
