Number Porting
Convert your BT number to your Netzen VoIP phone
is now possible to port all BT geographic area code telephone numbers. Non-geographic BT numbers beginning with 08 (e.g 0800, 0870, 0845) can also be ported, as can 08 numbers supplied by Energis.
To port your number Please call us directly on 01225 588 588 or email us at porting [ at ] netzensolutions.com we will then explain the process to you and email / fax you the relevent forms.
NB: Any numbers with services attached/associated to them (e.g. fax, broadband, alarm systems) will be ceased when the number is ported over to Netzen. If this is the case you must arrange to transfer these services to new number with BT before attempting to port.
The following circumstances will not prevent the export of a number:
- Change number Interception (CNI)
- Permanent call diversion
The following circumstances will prevent the export of a number:
- Numbers associated with a temporary service
- Inactive numbers
- A non-BT account number (unless with another VoIP provider*)
- A non-BT provided number, for example an NTL supplied number ported to BT (unless with another VoIP provider*)
* To port a SIP number we would require a letter of authorisation from the losing provider and also the letter of authorisation customer.
Porting VoIP numbers from other providers
We are able to port numbers from some existing VoIP providers such as Sipgate (providing you have their agreement to do so.)
This takes up to 3 days to complete once permission is granted.
At present we are unable to port any numbers from NTL.
