If you want to test Dialzara with your existing business number, distinguish forwarding calls from moving the number to another provider. To keep answering the phone yourself and use an AI receptionist for overflow, start by checking conditional forwarding with your current carrier.

Forwarding and porting solve different problems

The official Dialzara site describes forwarding an existing business number to its receptionist. Ask for current setup instructions for your carrier and country. Forwarding generally routes calls from a number retained at your carrier to a destination number. Porting moves the number between providers. Confirm eligibility, timing and account requirements before choosing either approach.

Write down who controls the existing number and how the current phone service is used. A shared reception number may also support outgoing calls, voicemail or messages. Changing incoming routing should not accidentally remove another workflow the business relies on.

Choose which calls should reach the agent

There are several routing choices: every incoming call, unanswered calls after a delay, calls when the line is busy or calls outside opening hours. Ask your carrier which conditions are supported and whether they can be combined. Use the carrier's current instructions rather than a forwarding code copied from another network.

Agree the answer delay with staff. If voicemail answers first, the AI destination may never receive the call. If the delay is too long, callers may abandon before forwarding begins. Test the whole path from an external phone, including the greeting callers hear while they wait.

Test each route rather than one successful call

SituationExpected evidence
Staff answer normallyThe call reaches the team without unnecessary forwarding
No one answersThe agreed destination receives the call after the intended delay
Line is busyThe caller follows the agreed busy-line route
Agent transfers to staffThe transfer reaches a destination that cannot loop back to the agent
Transfer is unansweredA useful message or callback task is captured and assigned
Caller identity is withheldThe conversation requests an appropriate callback number

A routing loop is particularly easy to miss: an agent transfers to the main number, which forwards straight back to the agent. Ask for a separate destination or an agreed bypass route where needed. Test from a second external number so caller recognition does not hide the problem.

Check what the next person sees

Call capture should leave a usable name, reason, callback number and owner. Compare a new enquiry, an existing customer chasing a job and a caller who asks only for a person. Staff should be able to tell an urgent callback from a general message without listening to every recording.

Where you need booking or CRM updates, request those tests separately. Keeping the phone number does not establish how the conversation reaches your other systems. Ask which connection is included in the proposed plan and who maintains it when your staff or scheduling rules change.

Compare carrier and platform costs together

Review the official pricing page and obtain current terms. Include any carrier forwarding charges, retained phone subscription, destination-number costs, usage and implementation. Verify outgoing caller ID and text-message handling independently; incoming forwarding does not establish either.

Before a trial, record the original routing settings and agree how to restore them. Make a test call after restoration as well. A workable fallback matters when the phone number is printed on vehicles, directories and customer paperwork.

Compare an overflow workflow with Sysevo

See the Dialzara and Sysevo comparison and Sysevo voice agents. Bring your carrier, number type and desired answer rules to a workflow discussion. Confirm supported routing for that setup before changing the live line.

Questions buyers ask

Does forwarding require transferring ownership of the number?

Forwarding and porting are different arrangements. Confirm the exact service with your carrier; a forwarding setup normally leaves the existing number at that carrier.

Why should we test voicemail as well?

If carrier voicemail answers before forwarding takes effect, the caller may never reach the AI receptionist. Check the complete timing from an external phone.

What is the most useful transfer test?

Ask the agent for a person, leave the destination unanswered and inspect what happens next. Check that the route cannot loop back to the same agent.
