TL;DR – Reseller VoIP Provider Guide
Interconnected VoIP providers must facilitate LNP for end users and execute valid porting requests without unreasonable delay.
Simple wireline-to-wireline and simple intermodal ports must be completed within one business day (with specific timing rules around when an accurate request is received).
Non-simple ports must be completed within four business days unless the customer or the new provider requests a longer timeframe.
For simple ports, carriers may require only the FCC’s standardized data fields (not a custom list of extra hoops).
FCC guidance explicitly applies LNP responsibilities to interconnected VoIP providers even when they obtain numbers indirectly through “numbering partners,” and it also applies to reseller scenarios.
Platforms like Viirtue pair porting workflow automation (LOAs, e-sign, status tracking) with quote-to-cash, so porting does not live in spreadsheets and inbox archaeology.

Reseller VoIP Provider: FCC Porting Rules You Need to Know Before You Choose a Platform
If you are evaluating a reseller VoIP provider, number porting is not a minor technical detail you can sort out later. It directly affects onboarding speed, early customer experience, support volume, and how fast you can start billing.
The FCC porting rules, also known as Local Number Portability (LNP), set clear expectations for how VoIP providers must handle port requests, timelines, and validation requirements, even in reseller and wholesale scenarios.
This guide breaks down what the FCC porting rules actually require, why they matter when choosing a reseller VoIP provider, and how to avoid platforms that turn porting into a constant source of friction instead of a scalable workflow.
1) What is a reseller VoIP provider?
A reseller VoIP provider is a platform or carrier relationship that enables your business (often an MSP, IT firm, or agency) to sell VoIP/UCaaS under a partner model, typically with wholesale pricing and partner tooling.
The part that gets glossed over: you are not just selling dial tone.
You are inheriting an operating model:
onboarding and provisioning
billing cycles and usage
That is why “rates” alone are not the right evaluation metric. Operational friction is the silent margin killer.
2) Why FCC porting rules matter when picking a reseller VoIP provider
Your first 30 to 90 days with a new customer usually include:
port requests
rejections due to data mismatch
cutover scheduling
“why are calls not routing yet” tickets
A reseller VoIP provider that handles porting poorly creates:
longer time-to-revenue
more support load
higher cancellation risk before the first invoice settles
FCC rules do not make porting effortless, but they do establish baseline obligations you can use as a standard when evaluating providers.
3) FCC porting rules explained for VoIP and resellers
Rule #1: Interconnected VoIP providers must facilitate porting without unreasonable delay
Under 47 CFR § 52.34, an interconnected VoIP provider has an affirmative legal obligation to take all steps necessary to initiate or allow a port-in or port-out (directly or through carriers it relies on) without unreasonable delay or unreasonable procedures that effectively delay or deny porting.
The FCC reinforced this point in a September 22, 2025 Public Notice, reminding interconnected VoIP providers that LNP obligations apply regardless of whether numbering resources are obtained directly or indirectly through numbering partners, and explicitly noting that these obligations extend into reseller relationships.
Why it matters to you: if your reseller VoIP provider is vague about porting ownership or blames “upstream” for every delay, that is a red flag.
Rule #2: Porting intervals are defined for “simple” vs “non-simple”
Under 47 CFR § 52.35:
Providers must complete a simple wireline-to-wireline or simple intermodal port request within one business day (unless the customer or new provider requests longer).
Non-simple wireline-to-wireline or intermodal port requests must be completed within four business days (again, unless longer is requested).
The same rule defines intermodal ports to include ports involving interconnected VoIP service, which is important because it squarely places VoIP porting into the timing framework.
There are also timing mechanics in the rule about when an accurate local service request must be received to be eligible for activation timing.
Rule #3: For simple ports, carriers cannot demand unlimited validation fields
Under 47 CFR § 52.36, a telecommunications carrier may require only the standardized data described in the rule to accomplish a simple port request, including fields like the ported telephone number, account number, zip code, desired due date, and others listed in the regulation.
Why it matters to you: extra “custom” requirements slow ports down and create rejection loops that you end up managing.
Rule #4: The obligation does not disappear when multiple providers are involved
The FCC’s 2025 Public Notice is especially relevant for modern channel and wholesale structures: it reminds providers that LNP obligations apply even when an interconnected VoIP provider relies on numbering partners, and it also reminds numbering partners of their role in facilitating LNP requests.
Translation: “It’s complicated upstream” is not a valid excuse for a broken porting experience.
4) The porting reality check: what causes most failures
Even when the rules are clear, the execution lives in the details. Most delays come from:
customer data mismatch (account name, address, account number)
missing or incorrect authorization documents
partial port complexities (what stays, what moves)
cutover planning mistakes
The best reseller VoIP provider is the one that turns this into a repeatable workflow, not a tribal knowledge exercise.
5) Porting readiness checklist: what to demand from a reseller VoIP provider
Use this as a practical evaluation rubric.
A. Workflow and visibility
Port request intake that forces clean data entry (not free-text chaos)
LOA generation and signature routing
Status tracking per TN with clear next steps
Firm Order Commitment (FOC) visibility and cutover scheduling discipline
B. Rule-aligned validation
Clear distinction between simple and non-simple ports
A process aligned to the FCC porting intervals framework
No “mystery fields” demanded for simple ports beyond what is reasonable for execution
C. Partner operations
A support model that does not dump every rejection on your team
Documentation and onboarding assets you can reuse across customers
D. Quote-to-cash connection
Porting touches billing. If your platform cannot connect quoting, ordering, provisioning, and invoicing, you get revenue leakage.
That is why reseller platforms built around quote-to-cash tend to win in the long term.
6) How Viirtue supports porting and reseller operations
Viirtue was built around the realities of reselling voice: quoting, onboarding, changes, usage, billing, and compliance workflows that have to scale. (Viirtue)
On the porting side, Viirtue content describes ViiBE as automating key pieces of the porting workflow, including LOAs, e-signatures, status tracking, and number ordering.
On the business side, the platform positioning is that you can run white label VoIP with automated billing and tax compliance workflows as part of the partner experience, with ViiBE included for partners.
If your goal is to choose a reseller VoIP provider that reduces operational drag, porting is one of the first areas where you will feel the difference.
Choosing a Reseller VoIP Provider Without Letting Porting Sink Your Growth
Choosing a reseller VoIP provider is not just a pricing or feature decision. It is an operational decision that shows up immediately in porting timelines, support tickets, and customer trust. The FCC porting rules give you a clear baseline for what must happen, but the real differentiator is how well a platform operationalizes those rules into repeatable workflows your team can actually manage. Providers that hide behind upstream complexity or manual processes turn porting into a margin leak and a churn risk.
Platforms built for resellers, like Viirtue and its ViiBE quote-to-cash foundation, treat porting as part of the full customer lifecycle, not an afterthought. If you want to scale voice revenue without scaling chaos, start by demanding a reseller VoIP provider that gets porting right from day one.

A reseller VoIP provider is a platform or wholesale relationship that lets you sell VoIP/UCaaS to customers under a partner model, typically with partner tooling for quoting, provisioning, and service management. (Viirtue)
Do FCC porting rules apply to interconnected VoIP providers?
Yes. FCC rules require interconnected VoIP providers to facilitate local number portability without unreasonable delay, including when they rely on numbering partners. (Legal Information Institute)
How long does porting take under FCC rules?
FCC rules establish that simple wireline-to-wireline or simple intermodal ports must be completed within one business day, while non-simple ports must be completed within four business days unless longer is requested. (Legal Information Institute)
What information can a carrier require for a simple port?
For simple port order processing, FCC rules provide standardized data fields and restrict carriers to those required fields (with an optional passcode field in certain situations). (Legal Information Institute)
Why do reseller VoIP businesses struggle with porting?
Because porting combines data accuracy, authorization, upstream coordination, and cutover planning. If your platform lacks workflow automation and visibility, the process becomes manual and error-prone.
