Paul,
IPCC contains a Spoken Name Upload feature that can associate a WAV file to the LDAP user. This will then playback the recorded file instead of the name spelling playback. That is the manual way which in IPCC 4.x is found in Tools, User Management, Spoken Name Upload.
I also believe there is a SNU.aef used for having the users call in and record their name for automatic upload. Let me do some research on that and I will post back.
Please rate any helpful posts
Thanks
Fred
