Is it possible to block (Inbound) a couple of telephone numbers either in the CallManager or VoiceGateway?
Fortunately blocking or restricting the calling party number is only possible for H323 using translation rules, this is not the case with CallManager:-
1. Configure Voice translation rule.
voice translation-rule 1
rule 1 reject /number_to_block/
rule 2 reject /number_to_block/
2. Configure Voice translation profile.
voice translation-profile Calling_Block
translate incoming 1
3. Assing the Voice translation profile to the incoming pots dial-peer.
dial-peer voice xyz pots
translation-profile incoming Calling_Block
Hope this helps.
