The correct answer is B. A route pattern contains dial plan information for calling the PSTN. Route patterns in CUCM define the dial plan digit strings that match outbound PSTN calls and direct them through a route list or gateway.
Question
After getting reports that users cannot make calls out to the PSTN, a network administrator opens the Cisco Unified Communications Manager Administration web page and begins to review route patterns. Why would the administrator look here when troubleshooting PSTN connectivity troubles?
Options
- AA route pattern contains a list of gateways that can reach the PSTN.
- BA route pattern contains dial plan information for calling the PSTN.
- CA route pattern contains the necessary privileges for calling the PSTN.
- DA route pattern contains a list of SIP trunks that can reach the PSTN.

Why each option
Route patterns in CUCM define the dial plan digit strings that match outbound PSTN calls and direct them through a route list or gateway.
A route pattern does not contain a list of gateways directly; gateways are associated via route groups and route lists, which are referenced by the route pattern.
A route pattern specifies the digit string (such as 9.@ for NANP or 9.011! for international) that matches a dialed number destined for the PSTN and associates it with a route list or gateway. If a route pattern is misconfigured or missing, calls to the PSTN will fail, making it the first logical place to verify dial plan correctness.
Calling privileges for PSTN access are controlled by partitions and calling search spaces, not by route patterns themselves.
SIP trunks are not listed within route patterns; like gateways, they are referenced through route groups and route lists that the route pattern points to.
