Number Porting

Keeping your numbers and porting them into express telephony from your current provider is a simple regulated process.


Porting numbers into Express Telephony is a straightforward process. Send us a copy of your latest phone bill with a list of the numbers your wanting to retain on your new Express Telephony VoIP PBX System. We will complete the Letter of Authority form required by OFCOM and send it to you to check, complete any missing information, sign and copy to your company headed notepaper and return to us to forward on to your carrier. 

The forms have information about the numbers you want to retain, the registered office address (where applicable) your current provider and details of where the line is currently installed at. We will use the copy of your bill from your current provider as proof of ownership of any number you wish to port and forward the forms over to your provider via the number owner.

The process takes 2 - 6 weeks to complete. If necassary we can forward calls from your old supplier to a temporary number where the delay waiting for the number port is too long



Express Telephony charge £10 per main billing number (or single line and number) for multi-line numbers we still charge £10.00 and multiple dedicated (DDI) numbers we chanrge £50 for 20 and £100 per 100. For larger number ranges please ask for a quote. To receive a quote simply contact us using the details below.
