We had a user leave the company and a request was made to forward their old extension to another user's directory number. I forwarded this under the DN settings in CUCM and it forwards correctly whenever anyone calls. However, when voicemail answers it is of the original voicemail and not to the transferred number.
Directory Number Settings (of original number)
- I removed the Voice Mail Profile to <None>
- Calling Search Space <None>
In Unity Connection (8.5.1)
- Edited Transfer Rules to Trasfer Calls from Greeting to Extension of new number.
