What must be configured in IPO to route calls to a phone number?

To route calls to a specific phone number in the IPO (IP Office) system, it is essential to configure the Incoming Call Route settings. This functionality allows the system to determine how incoming calls are handled and where they are directed based on criteria such as the caller's number or the time of day.

Incoming Call Routes define the rules for directing calls to various extensions, groups, or external numbers. This includes setting up parameters like the destination number, the type of routing (e.g., to an extension or an external phone number), and the conditions under which these routes are activated. Properly configured Incoming Call Routes ensure that callers reach the intended recipient effectively and promptly.

Other options such as voicemail settings, billing configuration, and software upgrade options do not specifically relate to the routing of calls. Voicemail settings deal with how messages are stored and accessed; billing configuration manages call charges and costs; and software upgrade options pertain to the versioning and features of the IPO system. Thus, these areas, while important for overall system functionality, do not directly impact the routing of calls to a phone number.
