Advanced call routing capabilities refer to the ability to route calls to the most appropriate destination based on a set of predetermined rules.

These rules can take into account a variety of factors, such as the time of day, the caller's phone number, the caller's location, or the type of call (e.g. sales, support, etc.).

Examples of advanced call routing capabilities that a VOIP phone system might have include:

• Time of day routing: Automatically routing calls to different extensions or voicemail boxes depending on the time of day. For example, during business hours calls may be routed to the main reception desk, while after-hours calls may be routed to an answering service.
• Caller ID routing: Automatically routing calls to different extensions or voicemail boxes based on the caller's phone number. For example, calls from VIP clients may be routed to a specific account manager, while calls from unknown numbers may be routed to a general voicemail box.
• Geographic routing: Automatically routing calls to different extensions or voicemail boxes based on the caller's location. For example, calls from within a specific area code may be routed to a local office, while calls from outside the area code may be routed to a national call center.
• Call type routing: Automatically routing calls to different extensions or voicemail boxes based on the type of call. For example, sales calls may be routed to a sales team, while support calls may be routed to a support team.
