Published by Keyboard Banger on

Let’s try both combinations. Once expanding the pattern 9999 to a PSTN number, and once blocking it.

configuring a routing translation pattern

We configure a translation pattern with the pattern 9999. The translation pattern has a Called Party Transform Mask of 9011442072431810.

Calling 9999 is successful.

configuring a blocking translation pattern

We take the same pattern, and set it to blocking. We can add a custom cause code.

And we try the call again. The line hangs up silently.

Trying to add a translation pattern that overlaps with a route pattern won’t be accepted by CUCM:
