Just wanted to point out that the Cisco Unity Bridge now has its own configuration and troubleshooting guide. It is available at:
This guide was released in conjunction with Cisco Unity 4.0(1). There's a few things in there that are 4.0(1) specific. However, the majority of configuration and troubleshooting information also applies to Cisco Unity 3.1(x) systems using the Bridge. Lots of stuff has been added, including when/how to configure an SMTP connector or special recipient policy for the voice connector in more complex Exchange topologies, how to enable and analyze traces for the Brooktrout TR114 board, lots more troubleshooting info, etc.
Anyone using the Cisco Unity Bridge with Cisco Unity 3.1(x) or 4.0(1) should find this newest guide really helpful.
Also note that the Cisco Unity Voice Connector for Exchange version 10.0(1) also released to CCO last week. This voice connector is supported for use with Cisco Unity 3.1(5) and later. Anyone currently using the Bridge with 3.1(5) will find the enhanced logging, and new performance logging, really helpful.
