====== Letter of Authority ======
The GNP Letter of Authority is usually required only for porting numbers which are part of a multi-line installation.

A multi-line installation generally falls under:
  * ISDN (both ISDN2e and ISDN30e variants)
  * Featureline
  * Auxiliary Line
  * VoIP enabled numbers from certain providers

Additionally, a GNP Letter of Authority will be required if you are porting your number from Skype.


===== Filling out the Letter of Authority =====
As the name implies, it is ultimately a letter giving SureVoIP authority to port your number and also obtain required information to enable porting of your number. Therefore, the LoA must be filled out in full and accurately.

//Losing Communications Provider//\\ 
This is your current provider. Please fill out the name and also the registered address. This is usually found on an invoice.

This information is required.


//Customer Details//\\ 
This section requires you to fill out your company details. 

//Requester's Details//\\ 
This is contact details for the person in your organisation who is responsible for porting the numbers. This person must have authority to make decisions regarding the porting request.

//Individual Numbers//\\ 
**Site address** must be filled out accurately. This is the address where the service is currently being provided (ie where the lines are physically located). Please don't forget the //post code//.

The address is still still required even if you are porting VoIP enabled numbers. If this information is missing then your order can not progress.

**Telephone Numbers to be ported** list the numbers here that you wish to port. Do not omit any numbers as this will cause delay.\\ 
Be sure to identify which number is the **main billing number**.


//DDI Range//\\ 
DDI ranges are typically blocks of 10 numbers, but are sometimes smaller. These numbers must be ported together and identified as a DDI block.


//Notes//\\ 
Put anything you feel may be helpful in this box.


//Signature and Date//
Don't forget to date, print your name and sign.

We can not guarantee that an electronic signature will be accepted so we suggest printing, signing by hand, then scanning back in.
