We have set up CUCM so that the ANI from the gateway is pre-pended with the external access code (9), so that when you hit the missed/received calls directory you can auto dial the number straight back. Sadly, this has the unwanted side effect that the ANI received by Unity now has a 9 in front of it, which is then posted on the email notifications to the user e.g. "you had a call from 902077551234" when what you really want is "you had a call from 02077551234". This is annoying the users who would like to dial the number back from their blackberry without editing the number.
Has anybody got a solution to this, either in CUCM, Unity, MS-Exchange or Blackberry?
