Complete Guide to VoIP Number Porting - Quick & Easy Steps

VoIP stands for "Voice over Internet Protocol."  Through the use of this technology, you can place calls online. It usually results in lower costs. That makes it an appealing option for business owners, especially now that many interactions are done digitally. Many VoIP services go hand in hand with features integrated with CRM software and social media. 

In contrast to landline telephones, which use the Circuit Switching Network, VoIP employs the Packet Switching Network. The main distinction between circuit switching and packet switching is that circuit switching establishes a phone connection using electrical circuits. In contrast, packet switching uses packets to send data over the Internet.

If you intend to make the transition to VoIP but would prefer to keep your existing number, you can opt for VoIP porting. VoIP porting is the process of transferring a phone number from your current provider to a new VoIP service provider. This term applies whether you are shifting from a traditional phone number carrier or a VoIP one. 

In this article, we'll walk you through the steps to port your VoIP number and the benefits it can provide for your business. 

Important Terms in VoIP

Before we get started, it’s necessary to get acquainted with the terms used to describe the complicated workings of VoIP technology. So let’s take a quick look at some of the common terms:

  • Codec - a device or software that converts analog audio signals into digital data and vice versa. This conversion is necessary to transmit audio over the Internet. Several VoIP codecs, including G.711, G.729, and Opus, are available, each with different compression rates and quality levels.
  • Session Initiation Protocol (SIP) - Session Initiation Protocol is used to establish and manage VoIP connections. SIP is used to initiate, sustain, and remove phone calls and settle call features.
  • Real-time Transport Protocol (RTP) - Real-time Transport Protocol sends audio and video data over the Internet. This protocol sends audio packets between VoIP call endpoints and guarantees that the packages are shipped in real-time and in the correct order.
  • Quality of service (QoS) - It is required for VoIP since it ensures that voice traffic takes precedence over other types of traffic, such as email or web browsing. Reducing inactivity, jitter, and packet loss can degrade a VoIP connection's quality.
  • Private Branch Exchange (PBX) - Private Branch Exchange is used within an organization to manage incoming and outgoing calls. It can be implemented using VoIP as a software-based system operating on a server
  • Analog Telephone Adapter (ATA) - A device used to link traditional analog phones to a VoIP network is known as Analog Telephone Adapter. That converts analog phone signals into digital data that may be sent over the Internet and vice versa.
  • Softphone - A softphone is a program that enables users to make phone calls. They can use their PC or mobile device to make VoIP calls.

Some of the benefits of VoIP numbers

Voice over Internet Protocol offers several benefits over traditional phone numbers, After reading through this section, consider trying it out for your business. The benefits of using VoIP numbers include but are not limited to the following:

  • Cheap to use

VoIP services are less expensive than traditional ones, particularly for long-distance and international calls.

  • Expandable

VoIP numbers are easy to adjust in terms of phone lines, which is ideal as your business grows or changes.

  • Versatile

VoIP numbers offer a wide range of features and options, such as call forwarding, voicemail, and call recording, making it more flexible to meet the specific needs of your business.

  • Mobility

Regarding portability, VoIP numbers are not attached to a physical location, meaning you can take your phone number anywhere. That means you can continue communication even when you're at a different location or constantly moving.

  • Service Quality

VoIP technology has innovated in recent years and now offers superior voice and video calls that are on par with traditional phone services.

  • Sustainable

Because VoIP technology consumes fewer resources than traditional phone systems, it is a more sustainable option for businesses looking to reduce their environmental effect.

  • Compatible with other services

VoIP services are usually integrated with other services and features. For example, many can be used alongside CRM software which helps you expand on the possibilities of understanding consumers and improving customer experience.

VoIP numbers are more affordable, flexible, and rich in features compared to traditional phone lines, making them a perfect choice for companies wishing to modernize their communication infrastructure and make it easier to communicate and be accessible.

How To Port Numbers

Now we know the advantages of having and using a VoIP-based number. We've gathered the steps to port your number to ensure you're ready when you choose to make the change. 

Inform your new VoIP service provider of your port requirement

Tell your new VoIP service, such as LimePhone, about your intent; you must port numbers over when signing your new contract. That may require an increased scope of work and an additional porting price.

Keep your current phone service to avoid disruptions

Keep your current phone service after you've decided on a new VoIP provider so you can port numbers across. Wait for a successful port transition before terminating your contract with your previous supplier. You may need to switch to a different provider rapidly at times. To accomplish this, contact your VoIP provider and request temporary phone numbers. These quick phone numbers can only be used to forward calls from your old phone service.

Obtain your account information to authorize a Letter of Agency

The Federal Communication Commission states that your former vendor is compelled by law to allow you to port, regardless of any remaining balance from a terminated contract. However, they must validate the request to ensure its authenticity. The correct account information must be included in the Letter of Agency.

Obtain your previous billing statements and documents to transition your phone service effortlessly. Make yourself available via phone or email if the VoIP porting team requires account information such as PINs, social security numbers, or EIN/tax identification.

Your phone service should be uninterrupted until your number is transferred to your new phone service.

Complete the necessary paperwork

You may need to complete some paperwork to authorize your phone number transfer. Your new provider will provide you with the necessary documents and instructions.

Hold off till the porting procedure is finished

When the paperwork is turned in, the porting process will start. The length of the transfer might range from a few days to a few weeks, depending on its complexity and the response of your current phone provider.

Verify the number

When the transfer is finished, test the phone number to ensure your new VoIP service provider can use it.

Porting VoIP Number Requirements

After signing the contract, you must provide your new vendor with a list of details to start porting your phone number.

You must provide the following information:

  1. A list of every phone number you have and any extensions you might have.
  2. Letter of Authorization (LOA) - This allows your new vendor to negotiate with your former vendor on your behalf. It reveals crucial information regarding who has authority over the number(s).
  3. Old vendor and account number - To finish the process, the two vendors will speak with each other.
  4. Copy of current phone bill - Provides further confirmation of phone number ownership and easily contains vital information for the new provider.

Potential impediments during VoIP Number Transferring

Your phone number is not portable

While porting phone numbers should be a simple process, there are occasionally snags.

When port numbers, you may encounter one of two types of difficulties.

  • Your telephone number is not transferable - Serious issues will prevent you from porting your phone number. While the FCC requires that numbers be portable, there are a few potential stumbling blocks:
  • Incomplete rate center - Your new provider still needs service in your area and help port numbers there.
  • If your phone number is no longer in service, portability is impossible.
  • There is no interconnect arrangement - VoIP providers must have an agreement with the telephone company that owns that phone number.

If you are in this circumstance, you must either find an alternative to transferring your number or choose a new one.

Other Potential Errors

The second group of potential issues is all fixable but time-consuming. These are some of the problems:

  • The phone line may be DSL - you may need another phone number unless the DSL provider allows for a dry loop. Always check with your DSL provider before migrating a DSL phone number.
  • Incorrect contact information - If your name and address do not match those on your order, you may be asked to show additional confirmation of phone number ownership. You can request rectification if the service address differs from the address on the porting request.
  • Number not found - A user error could prevent the number from being seen when entering a phone number.

How long does it take to port a phone number?

As previously said, transferring phone numbers should be a simple process. Phone number porting typically takes 2-4 weeks to complete.

Toll-free numbers (800, 866, 888) may take longer to port. During this time, your service should not be disrupted.

Wait to cancel service until the porting is finished

You can discontinue services with your old provider once your number has been ported and your new provider handles the route to your phone number.

Remember that your old supplier cannot retaliate or block the port-out request. You may still be responsible for any outstanding balances and applicable termination costs. Expect it to stay strong since it probably won't.

Keep your company phone service's integrity

Transferring a phone number is not difficult; it exists for a purpose. Requests must be authenticated to prevent fraud and abuse. We may all rejoice that the days of telecom firms enslaving your phone number are over.

Work with a reputable VoIP service provider like LimePhone to ensure a smooth and successful porting process.

How to Port VoIP Numbers to Google Voice?

The general steps to move your VoIP number to Google Voice are as follows:

  • Launch Google Voice. Set up Google Voice if you don't already have one. When you sign up, you'll be given a free phone number, but once the port request is approved, the ported number will take its place.
  • Select Settings from the top-right corner of the screen, then Account.
  • Select Get Started after clicking Port a number from the Port a number to Google Voice section.
  • Enter the number you wish to port and request a 6-digit verification code by phone or SMS.
  • Enter the code here.
  • If your phone number is portable, Google Voice will request carrier account information. The majority of these details can be found in your phone number account.
  • Examine the information and then make the payment.

Once the porting procedure is complete, your VoIP number will be linked to your Google Voice account, and you will be able to use it to make and receive calls, send and receive text messages, and do other things. While compared to a regular landline or mobile number, there may be some limits or variances in features and functionality while utilizing a ported VoIP number with Google Voice.

How to Check Phone Number Portability?

To check if your phone number is portable to a different service provider or platform, you can follow these steps:

  • Contact your current service provider and ask if your phone number is portable. Your provider will be able to confirm whether or not your number can be ported and any requirements or fees associated with the process.
  • Check with the new service provider or platform to which you intend to migrate your phone number. They should clarify whether or not your number is portable and any regulations or expenses that may be incurred during the process.
  • Use a third-party portability checker.

It's important to note that porting a phone number may involve fees or other requirements and may take several days to complete. It's also essential to confirm that you understand any limitations or differences in features and functionality when porting a number to a new service provider or platform.
