I have a customer with 2 sites each has their own express 4.2 call agent and Cue flash for voicemail. the wan link works fine for voice calls between the 2 sites. However you cannot leave a voicemail for any user at either site. Intrasite vm is fine and also pstn vm is fine. but any intersite vm, the call is dropped. I have attached config, I am sure I have missed something.
This is likely a codec/transcoding issue here. CUE only does G711 and if the calls are coming in across the WAN as G729a there is a need in this setup for local Transcoding.
Codecs and Transcoding
Cisco Unity Express supports only G.711 voice streams, so all calls made into the system (including those from IP phones, PSTN gateway ports and any other VoIP equipment in your network) must use G.711 if they enter the AA or voice mail pilot numbers that terminate on Cisco Unity Express.
If you require that G.729A calls traverse IP segments of your network between sites, and that these calls forward or dial direct into Cisco Unity Express AA or voice mail, then you must use a transcoding resource collocated with Cisco Unity Express to change the voice stream from G.729A to G.711 before the voice stream enters the AA or voice mail pilot numbers.
