Chapter 7 VPIM Networking

Maintenance

•The audio format in which the remote voice messaging system can send and receive VPIM messages. Some voice messaging systems support only the G.726 format for VPIM messages, but you will need to consult the documentation of the remote voice messaging server to be sure.

•Network bandwidth.

We recommend that incoming VPIM messages be stored in the same audio format that the local Cisco Unity server(s) use for recording and playing messages. However, if you want incoming VPIM messages to be stored in some other audio format, you will need to verify that the applicable codec is installed on all Cisco Unity servers and on other computers that access these messages. In particular:

•If your organization has multiple Cisco Unity servers networked together, all of the Cisco Unity servers must have the codec installed.

•If subscribers use ViewMail for Outlook or the Cisco Unity Inbox to listen to messages, the codec may need to be installed on each subscriber workstation.

The Voice Connector converts the audio format of incoming and outgoing VPIM messages according to the settings on the VPIM delivery location. The Voice Connector requires both the codec that the VPIM message is being converted from and the codec that the VPIM message is being converted to. Depending on the audio format conversion, you may need to install the applicable codec on the Exchange server on which the Voice Connector is installed, as follows:

•G.711 and GSM 6.10—The Voice Connector uses the codecs that Windows installs. You may want to verify that the codecs are still installed on the Exchange server.

•G.729a and G.726—The Voice Connector uses its own copies of the G.726 and G.729a codecs, so these codecs do not need to be installed on the Voice Connector Exchange server. (Note that the Voice Connector will add a RIFF header to an incoming message in the G.726 format if the header is missing. Without the RIFF header, Windows-based audio players will be unable to play messages.)

•OKI ADPCM—To convert messages from the OKI ADPCM audio format, the OKI ADPCM codec must be installed on the Exchange server on which the Voice Connector is installed.

•Other codecs—To convert messages from other audio formats, the applicable codec must be installed on the Exchange server on which the Voice Connector is installed.
