I have a configuration with 2 sites. I have UC540 at the primary site, and a UC520 at the secondary site. The VPN is up and passing data traffic as well as voice traffic, i.e. users can dial each other's extensions by using the Inter-site prefix and Location prefix.
The problem I am having is when a user at the primary site tries to forward a voicemail to a user at the secondary site. When they attempt to send the voicemail, they get a message that the extension does not exist.
Is there particular configuration in CUE that needs to be done in order for this to work, or should it just work?
