Flexible Number & Rerouting

The Flextel service give you very powerful call routing controls. Unlike most other services, with Flextel, you can route one flexible number to another. This lets advanced users build very powerful applications using our building blocks.

However with flexibility comes the risk of complexity.
To assist you in tracking what you are constructing we supply Route Analysis. This helps you avoid endless call loops and also exceeding set limits on the number of simultaneous reroutes that can be supported. This limit is set to 10 at this time. If you think you want more, simply write to us, explaining why, and we will pass it on to our technical team for consideration.

Route Analysis

Route Analysis is split into two parts. The detail of which you will find on the bottom of the reroute screen. To view the full details of this analysis, click view details in the top right of the Route Analysis box. The website will remember your setting while you remain logged on.

1. Call Path Analysis
This shows the path the call could take when a call is dialled to the current number. You should see indicating that there are no errors.

2. Inbound Number Analysis
This checks if you have any Flextel number in your account(s) pointing towards the current Flextel number. You should see the total count of numbers plus indicating that there are no errors.

Error Detection

If the system detects a routing error, it will automatically expand the view to show those errors and display against those numbers with a fault.

No Errors?
If there are no errors, you will only see green icons such as: , , , etc. To view all the numbers, related to the current number, you must click the in the top right of the Route Analysis box.

Further Help

Faults can be complicated in complex applications, so if you are confused, please give us a call during office hours and we will try and help. You may even be able to suggest improvements to this powerful feature.


Fixed Fee Calls: Some services which have a very high initial charge cannot be connected.

Premium Rate Services (Information/Adult etc.): These services cannot be connected and will not be connected in the foreseeable future.


To protect your service from attack, you can set email notifications for each time a destination number is changed. So you will always know where your calls are being directed and the settings you have selected for DND or ICD etc.

See Call Notification for more information.


Did you note the PIN information correctly?
We recommend that all PIN information is either printed or saved to disk for future reference.

Did you activate your new Flextel number after reserving it?
If you did not connect (activate) your Flextel number within 24 hours of reserving it, the number may have been released back to stock.
If you have only just reserved your number, check your inbox (or possibly your spam/junk mail folder) for an email from customer.support@flextel.com containing your unique number activation link.


To use the automatic rerouting service you need to call from a phone that has a keypad with a star * key and dials using touch tones. To check if you have the right sort of phone, lift the handset and dial 0370 321 0000. If you hear tones as you dial then you have a touchtone phone, if not and you hear clicks instead, then you probably have not got a touchtone phone or it needs to be set into 'tone' mode.

In some cases the phone will not send tones until either the star * key or a key marked POT, MF or TONE has been pressed. This 'tone' key should only be pressed after normal dialling has been completed, such as when ringing is heard.

If you do not have access to such a phone or have any queries then call our customer service line during normal office hours on 0370 321 1000 and we can advise you or make the changes for you.
