Map the normal route and the exceptions
A hosted PBX can support agreed call menus, queues, business-hour rules and transfers, subject to the chosen configuration. The design should match the customer’s reason for calling rather than copying the organisation chart. Avoid asking callers to navigate several menus when one clear question would route them correctly.
Document working hours, public holiday handling, busy conditions, unanswered destinations and out-of-hours messages. Confirm which calls go to your own staff, which reach Britixo agents and which require a callback. Extended-hour agent cover is a separate staffing requirement; a phone system being available does not mean agents are staffed around the clock.
Make transfers and overflow deliberate
A transfer needs a valid destination, an expectation about availability and a fallback. Where appropriate and technically supported, the receiving person can be given context before the customer moves across. If they cannot answer, the agent should know whether to take a message, create a task or offer an approved callback.
Overflow rules can use your existing team first and route to the agreed service when specified conditions apply. Forwarding charges, provider limitations and caller information must be checked. Number porting also needs its own plan; we do not assume a live business number can be moved instantly or without coordination.
Test before customers rely on it
Test the actual routes, not just one successful call. Include busy destinations, an invalid transfer, after-hours behaviour and an unavailable integration. Confirm the displayed caller ID and what information remains visible when calls are forwarded. Agree who can change the routing and how urgent faults are reported.
An illustrative overflow setup might send unanswered enquiries from your office to an agent session and create a callback task when the session is closed. The precise triggers, waiting behaviour and capacity are part of the approved design. Response-time targets and resilience commitments require an explicit service agreement.
