Question

To verify that proper digit manipulation is being applied when using called party transformation patterns, which Cisco IOS command do you use from the router or voice gateway?

Options

Ashow voice ccapi inout
Bdebug voice ccapi in
Cshow voice ccapi
Dshow voice ccapi in
Edebug voice ccapi inout
Fdebug voice ccapi out
Gshow voice ccapi out

Explanation

'debug voice ccapi inout' is the Cisco IOS command used on a router or voice gateway to capture real-time call control API events for both inbound and outbound call legs. This command reveals the digit strings as they arrive and leave the gateway, allowing a network engineer to confirm whether called party transformation patterns are correctly manipulating digits. The 'show' commands (A, C, D, G) display static information and do not capture live digit manipulation events. 'debug voice ccapi in' (B) and 'debug voice ccapi out' (F) are only single-direction and would miss half the picture; 'inout' captures the full transformation flow.
