Ok,
after some investigation and looking at the AC logs im seeing the issue. im using my Unity as the Autoattendant and it forward the voicemail DN (7XXX) to the IPMA RP as the caller id and then i see the actual caller id number. Ive tested the filters by placing 7XXX as the patterns and the filters work perfectly.
therefore, the question is now, is there anyway to not forward the Voicemail DN's but the actual calling party number?
your assistance would be greatly appreciated.
thanks in advance
