Problem with the See "Servicing the Network Call Processor battery on the NCP. Battery" on page 197. NBX NetSet is very slow in responding. Your network uses a proxy server for Internet access. A common networking practice is to employ a proxy server to shield your network from intrusion by unauthorized users. However, communications with NBX NetSet do not need to pass through the proxy server. To speed access to NBX NetSet, configure your browser to access the NBX system without going through the proxy server. All greetings and prompts are missing. For example, calling the Auto Attendant or a user's mailbox produces silence instead of the expected greetings. The wrong message compression format was selected. Prior to R1.1.0, all audio used MuLaw compression. With R1.1.0, audio, that is, any prompt, message, or greeting, was recorded using ADPCM compression. If you are running R1.1.0 or higher, you must leave the compression format set to ADPCM. The ability to select the format allows you to migrate existing data into an older database for backwards compatibility. In release R2.6 and all later releases, the compression is set to ADPCM and you cannot change it. Caller ID information is not appearing when an outside call arrives. Your local telephone company is not providing Caller ID service to you. Caller ID is typically an optional service which you must order from your telephone company. You may be able to see caller ID by number or by name (or both) depending on the service your telephone company provides. You are answering the telephone before the Caller ID information is fully received. Caller ID information does not appear immediately. It usually appears between the first and second rings. If you answer the call too quickly, the information is never received.
