Simple, Usage-Based Pricing
Pay for what you use. No contracts, no activation fees, no minimum term. Start with a 30-day free trial and $25 in credit.
Three Components. One Simple Bill.
Power-T.38 pricing has three parts: your SIP trunk, your fax numbers, and your usage. That’s it. No setup fees, no activation charges, no minimum term. You start with a 30-day free trial and $25 in credit — enough to put real fax traffic through the network before committing to anything.
Every fax page takes roughly one minute to transmit, so your usage cost is predictable: multiply your expected monthly page volume by the per-minute rate for your traffic type and you’ll have a close estimate of your usage bill.
Power-T.38 Pricing
Most customers need one SIP trunk. Each trunk supports unlimited concurrent calls across all your fax numbers. A second trunk is required only if you need to connect a second SIP device or server.
At least one fax number per SIP trunk is required. Your first number becomes the billing telephone number (BTN) for the account.
Each fax page takes roughly one minute. Usage is billed in minutes, the same way traditional phone calls are — even though T.38 is a data protocol, not voice.
Volume Discounts
Volume discounts are available for usage above 1,000 minutes per month. Discount tiers are based on your committed monthly volume and are discussed directly with our sales team — we don’t publish a rate sheet, because the right arrangement depends on your specific deployment and usage patterns.

If you’re a voice service provider, ITSP, or UCaaS platform looking to offer reliable T.38 fax to your customers, you’re in the right place. T38Fax works directly with service providers to offload fax traffic — you maintain the customer relationship, we handle the T.38.
Wholesale pricing is available for service providers who can meet volume commitments. Rates are usage-based and structured around your call volume, not fixed seats.

Each fax page is roughly one minute. This makes cost estimation straightforward: multiply your expected monthly page count by your per-minute rate and you’ll have a close estimate of your usage charges before you start.
Usage-based pricing means no bill shock. There is no flat-rate or unlimited plan. Your charges scale directly with your fax activity — if you send more, you pay more; if you send less, you pay less. For operations with predictable volume, this is typically more cost-efficient than a flat-rate plan sized for peak usage.
T.38 transmissions are billed in minutes — not pages, not kilobytes. Even though T.38 is a data protocol, it operates in real time like a phone call. Billing in minutes is the industry standard and makes your costs directly comparable to traditional POTS-line fax.
A second SIP trunk is only needed for a specific reason. If your setup involves two separate SIP devices or servers that need to connect to your T38Fax account simultaneously, you’ll need a second trunk. One trunk handles the vast majority of deployments.
Start with $25. No Commitment.
Every new account starts with a 30-day free trial and $25 in credit — enough to run real fax traffic through the network and confirm everything works with your specific equipment and configuration.

Contact SalesFrequently Asked Questions
- A SIP trunk is your connection from T38Fax to your fax equipment — your fax server, ATA gateway, or IP-PBX. One trunk is enough for most customers: it supports unlimited concurrent fax transmissions across all your fax numbers. A second trunk is required only if you need to connect a second SIP device or server to your account.
- Your bill has three components: the SIP trunk fee ($7/month per trunk), your fax number fees ($2/month per local number, $5/month per toll-free), and usage charges based on minutes used. Each fax page takes approximately one minute to send or receive. A 10-page fax to a US number uses roughly 10 minutes of outgoing usage, billed at $0.025/minute.
- Yes. Volume discounts apply to usage above 1,000 minutes per month. Contact our sales team to discuss discount tiers for your volume.
- No. T38Fax uses usage-based pricing — you pay for the minutes you actually use. There is no flat-rate plan. For operations with predictable volume, we recommend estimating your monthly minutes (roughly one minute per fax page) to model your costs before starting a trial. Our sales team is happy to help.
- Your account stops working unless you activate it to a paid plan. There is no automatic conversion — you decide if and when to continue. No credit card is required to start, and the $25 trial credit is yours to use during the 30-day period.
- T.38 fax transmissions are billed in minutes, the same way traditional phone calls are billed — even though they are data, not voice. Each fax page takes roughly one minute to transmit, so minutes and pages map closely for most operations.
