I'm running CUCME on a 2921 with ios 15.0(1). I'm wondering if it is possible to block incoming anonymous/unknown numbers from our PRI and if so, how I'd go about implementing it?
You can use "Call Blocking Specific Calling Numbers" in below link.
Please rate Helpful posts.
So applying a rule similar to
voice translation-rule 1
rule 1 reject /Unknown/Should work?
Apparently it does not work.
VOICE(cfg-translation-rule)#rule 1 reject ?
/WORD/ Matching pattern
VOICE(cfg-translation-rule)#rule 1 reject /Unknown/
% Invalid input detected at '^' marker.
Finally got it working with the following:
voice translation-rule 6
rule 1 reject /^$/
rule 2 reject /[^0-9]$/
