VoIP gateway prices vary with three specifications: the number of voice ports, the number of SIM slots, and the network technology. A 4-port gateway with 4 SIM slots is a small-office device; a 32-port gateway with 512 SIM slots is a carrier-scale appliance. Understanding how price scales with these specifications helps a buyer match hardware to real call volume without overpaying for unused capacity.
This article is a price guide to the Telarvo VoIP gateway lineup. It lists the current models, explains what drives the price difference, and gives practical guidance for budgeting a voice gateway purchase.
The Telarvo VoIP Gateway Price List
Telarvo sells the following SK VoIP Gateway models on its store:
| Model | Ports / SIM slots | Price (USD) |
|---|---|---|
| SK VoIP Gateway 4-4 | 4 / 4 | $260.00 |
| SK VoIP Gateway 8-8 | 8 / 8 | $480.00 |
| SK VoIP Gateway 8-32 | 8 / 32 | $620.00 |
| SK VoIP Gateway 16-16 | 16 / 16 | $899.00 |
| SK VoIP Gateway 16-64 | 16 / 64 | $1,050.00 |
| SK VoIP Gateway 16-128 | 16 / 128 | $1,200.00 |
| SK VoIP Gateway 16-256 | 16 / 256 | $1,450.00 |
| SK VoIP Gateway 16-512 | 16 / 512 | $1,550.00 |
| SK VoIP Gateway 32-32 | 32 / 32 | $1,550.00 |
| SK VoIP Gateway 32-128 | 32 / 128 | $1,850.00 |
| SK VoIP Gateway 32-256 | 32 / 256 | $2,300.00 |
| SK VoIP Gateway 32-512 | 32 / 512 | $2,520.00 |
| SK VoIP Gateway 32E-SIM | 32 / eSIM | $3,100.00 |
Most models above $620.00 include free shipping in the store listing. The eSIM model is the most expensive because embedded SIM provisioning adds capability beyond physical SIM slots.
What Drives the Price of a VoIP Gateway
Three factors explain the price ladder. The first is port count: each additional voice port adds a GSM/LTE module, which is the most expensive component in the device. Moving from 4 to 8 ports roughly doubles the radio hardware, and the price reflects that. The second is SIM slot density: a 16-port chassis with 128 SIM slots costs more than a 16-port with 16 slots because of the additional SIM management circuitry and carrier interfaces. The third is technology: 2G/4G-capable modules and eSIM support carry a premium over simpler designs.
The relationship is not linear. The 16-512 at $1,550.00 is only $350 more than the 16-128 at $1,200.00, because SIM slots are cheaper than voice modules. A buyer who needs number diversity rather than call concurrency can get a large SIM pool at a modest additional cost.
Comparing Prices Across the Telarvo Hardware Range
The VoIP gateway price list sits between two neighboring product families, and comparing them helps put the figures in context. A GOIP16 voice bridge costs $620.00 for 16 ports with SIM bank integration, making it the value choice for pure voice conversion. An SK-SMS Gateway 64-512 costs $2,480.00 for the SMS-focused 64-port chassis, which is close to the price of a 32-port VoIP gateway with maximum SIM density. A 32-port VoIP gateway with 512 SIM slots at $2,520.00 is the voice counterpart of that SMS machine.
The practical rule is to buy the family that matches the primary workload. If the operation is voice-first, the VoIP gateway price is the relevant comparison; if it is SMS-first, the SMS gateway line offers better value per port. The two families share the SIM management ecosystem, so a mixed operation can standardize on one SIM inventory while using both gateways.
Total Cost of Ownership for a VoIP Gateway
The list price is the visible cost, but a complete budget includes four more items. SIM plans are the largest recurring cost: each active SIM needs a voice plan, and the price varies by operator and country. Shipping is a one-time cost (free on most models above $620.00, via DHL or FedEx with 5–10 business days typical transit). Number provisioning may involve activation fees from operators. Finally, support beyond the included 7×12 assistance is available through the vendor for fleets that need dedicated engineering time.
When comparing a $260.00 4-port gateway with a $2,520.00 32-port gateway, the hardware difference is roughly $2,260.00, but the operating costs scale differently. The larger unit replaces multiple smaller ones, so power, space, and management overhead are lower per port. For an operation planning to grow, the larger chassis often has the lower total cost of ownership over a three-year period.
Seasonal and Growth Budgeting
Voice workloads are rarely flat. A call center may run at 80% capacity in an average month and at 100% during peak weeks; a seasonal business may see call volume triple for a quarter. Budgeting should size the gateway for the peak, not the average, because a gateway that is undersized during the peak queues calls and hurts service levels.
The same logic applies to SIM inventory. A pool sized for average volume will hit per-number limits during peaks. Telarvo’s SIM pool products let an operation add numbers independently of gateway ports, so the growth path is to add SIMs for peaks and add ports only when the concurrent call requirement grows permanently.
How to Get an Accurate Quote
The store lists standard prices, but the accurate figure for a deployment often differs because of SIM plans, routes, and configuration. Telarvo’s sales team at sales@telarvo.com provides custom quotations for fleets and bundles. A useful quote request includes the number of concurrent calls needed, the countries where calls originate and terminate, the target number of SIMs, and whether the operation also needs SMS or route services.
With those inputs, the vendor can recommend a model, confirm the SIM and shipping costs, and assemble a hardware-plus-route package where appropriate. The 12-month warranty and 7×12 support are included in every purchase, so the quote reflects the full cost of getting the gateway into production.
Price Differences Between SMS and Voice Gateway Lines
Comparing the VoIP price list with the SMS gateway list clarifies where the money goes. An SK-SMS Gateway 16-128 costs $970.00, while an SK VoIP Gateway 16-128 costs $1,200.00 — a $230.00 difference for the same port-and-SIM profile, reflecting the voice codec and signaling hardware on the VoIP model. At the top end, the SK-SMS Gateway 64-512 at $2,480.00 is priced near the 32-port VoIP gateway with 512 SIMs at $2,520.00, which shows that the SMS and voice families converge in price as density grows.
The lesson for buyers is to price the family that matches the workload. A team that needs both voice and SMS should compare the combined stack — for example, an 8-port VoIP gateway plus a dedicated SMS gateway — against a single hybrid unit, because the total cost and the capacity profile differ. Telarvo’s sales team can prepare both options for a given requirement.
Financing and Order Timing
VoIP gateway purchases are capital investments, and order timing matters for budgeting. Telarvo ships within two business days and typically delivers in 5–10 business days, so a purchase made in one month can be in production the same month. For fleets, ordering in batches can simplify logistics, and the sales team can schedule shipments to align with site readiness.
The warranty clock starts at delivery, not at order, so buyers who purchase before a project is ready should confirm the delivery timeline. Most organizations order the gateway, complete SIM provisioning during transit, and schedule installation for the delivery week. That sequencing keeps the project moving without idle hardware.
Common Budgeting Mistakes
Three mistakes show up in gateway budgets. The first is buying ports instead of SIMs: teams that overestimate concurrent call needs buy a large chassis but run out of numbers, when a smaller chassis plus a SIM pool would cost less and serve better. The second is ignoring SIM plan costs in the comparison, which makes the hardware price look dominant when the plans are actually the larger recurring expense. The third is under-budgeting for the network side — switch ports, power, and UPS — that a production voice deployment needs.
Avoiding these mistakes is mostly a matter of planning against real call volume and SIM needs rather than against the spec sheet. The price list in this article is the starting point; the quote from the sales team, with SIM and shipping included, is the number to budget against.
A Worked Cost Comparison: 4-Port versus 32-Port
Run the numbers on a realistic comparison. A 4-4 gateway costs $260.00; a 32-512 costs $2,520.00. The smaller unit supports 4 concurrent calls with 4 SIMs; the larger supports 32 concurrent calls with 512 SIM slots. If the operation runs 10 concurrent calls at peak, the 4-4 is undersized and a second unit would still fall short, so the comparison favors the larger chassis despite the price difference. If the operation runs 4 calls and expects to stay there for two years, the 4-4 is the efficient purchase.
Add the SIM plans: 4 plans versus 512 plans changes the monthly cost substantially, and that is where the pooled approach helps. An operation that needs 512 numbers but only 16 concurrent calls can choose a 16-512 gateway instead of a 32-512, saving $350.00 in hardware while keeping the same SIM capacity. The worked example shows why the model number, not the price, is the decision input.
How to Budget for a VoIP Gateway Purchase
For a small office with a handful of concurrent calls, the 4-4 at $260.00 is the lowest-cost entry. Growing operations that need multi-line support and SIM rotation typically step up to the 8-32 at $620.00 or the 16-64 at $1,050.00. Call centers with 20 or more agents should budget for the 32-port tier, from $1,550.00 to $2,520.00 depending on SIM density.
Two costs are easy to miss in a gateway budget: SIM cards and shipping. SIM costs are recurring and depend on the operator plans chosen for each market. Shipping from Telarvo is via DHL or FedEx with typical transit of 5–10 business days; most mid-range and high-end models include free shipping. The 12-month warranty and 7×12 support are included in the list price.
When a Higher-Priced Model Pays for Itself
A 32-512 at $2,520.00 costs roughly five times a 4-4 at $260.00, but it supports 32 concurrent calls and 512 SIM slots in a single appliance. For an operator running a voice service with real volume, the higher model replaces several smaller units and the associated management overhead. The deciding question is not the price per unit but the price per concurrent call and per managed SIM, which favors larger models as volume grows.
