In translation pattern, what happens when digits match?

• A. The digits are transformed according to the pattern without consuming a gateway.
• B. The digits are forwarded to voicemail.
• C. The digits are transformed for a gateway.
• D. The digits are ignored and dialing continues unmodified.

Answer: (C)

Dialed digits are rewritten to the form the next hop (typically a gateway) expects. When digits match a translation pattern, the pattern’s replacement rules are applied, transforming the digits before the call is routed to the gateway. This rewriting is how internal numbers are mapped to external or gateway-specific formats. It’s not about voicemail, and it’s not a matter of continuing unmodified; the point of a translation pattern is precisely to transform the digits for the gateway.
