Hi, I think translation rule should be:

rule 1 /^21520/ //

Haven't checked your config beside that.

Seems fine. Check with "debug isdn q931" and "term mon" which number are you receiving. The you can also check with "debug ccapi" what happens with the call.

how many digits is the telco sending to you?

many of them already send the last 4 digits so you don't need to apply any translation rules

a debug would tell you that
