Many locations that have implemented VOIP solutions require that there be a telephone line local to each physical location, through which callers can access 911. In the example system’s case, all of a location’s 911 calls will be routed through a specific trunk-group, which has a single POTS line member. That gets the caller to 911. But what happens if the PSAP doesn’t get the address, or the caller hangs up before speaking to the 911 call taker?
There are occasionally times when you wish to directly leave a message in someone’s voice mailbox, without first ringing their phone. Or, more often, you wish to transfer a caller directly to someone else’s voice mailbox without disturbing the called party. This solution allows for both of these situations. The vector simply asks you what mailbox number you wish to leave a message for, and then transfers you to that mailbox.
Every PBX needs to be able to tell its users when something’s gone awry. CM provides the ability to use announcements for intercepting.
From time to time, you might find that you need to be able to dial an extension (or DID) that transfers the caller directly to a voice mailbox that belongs to a specific (different) extension.
This post is merely a log of a particular troubleshooting experience initiated by CM IPMEDPRO alarms.
