Free SIP Trunking
— Really Free

IPComms SIP trunks are genuinely free. $0 per channel, no contracts, no setup fees. You only pay for phone numbers starting at $1.50/mo and per-minute usage. Not a trial. Not a gimmick. This is how we have done business since 2002.

What "Free" Actually Means

No gimmicks. The SIP trunk itself costs nothing. Here is exactly what you pay for and what you do not.

Always $0

  • SIP trunk / channel fees
  • Account setup or activation
  • Contracts or commitments
  • Cancellation or termination fees
  • Concurrent channel limits
  • Number porting fees
  • TLS/SRTP encryption

What You Pay

  • $1.50/mo Local DID phone number
  • $2.00/mo Toll-free number
  • $0.010 Per minute outbound
  • $0.009 Per minute inbound

A small business making 1,000 minutes of outbound calls per month with one local DID pays approximately $11.50/mo total. No trunk fees on top of that.

Not All "Free SIP Trunks" Are the Same

When you search for a free SIP trunk, you will find three types of offers. Only one of them works for production traffic.

Community / Hobby Free Trunks

Shared servers, 300–500 minute monthly caps, no encryption, no SLA, community-only support. Fine for a home lab, unusable for a business. Uptime can dip below 95%, meaning over 36 hours of downtime per month.

Trial-Period Free Trunks

Providers like Twilio or Flowroute offer 30–90 day credit-based trials. Useful for evaluating their platform, but the "free" disappears the moment the trial ends. Full pricing kicks in with per-channel fees, monthly minimums, and often long-term contracts.

IPComms — Permanently Free Trunks, Enterprise Grade

IPComms does not charge trunk or channel fees. Period. You pay only for phone numbers and per-minute usage. This is not a trial or a loss leader — it is our business model, and it has been since 2002. You get the same geo-redundant infrastructure, TLS/SRTP encryption, E911 support, and real human support that enterprise customers use in production.

Geo-redundant infrastructure across multiple data centers. Less than 4.3 minutes of downtime per month — backed by our service level agreement.

E911 Emergency Services

Full E911 support with automatic location routing. Stay compliant and keep your team safe. Not available on community free trunks.

Real Human Support

Phone, email, and live chat support from SIP engineers — not chatbots or community forums. Help when you need it.

Standard SIP protocol. Compatible with Asterisk, FreePBX, 3CX, FreeSWITCH, Teams, and more.

Who Uses Free SIP Trunking?

IPComms free SIP trunks work for testing and production alike. Here is who uses them.

Developers & Lab Testing

Need to test SIP trunk integration with Asterisk, FreePBX, or your own application? Sign up, grab a DID for $1.50, and start testing in minutes. No credit card required for account creation, no trial clock ticking.

Small Businesses

Traditional providers charge $15–25 per channel per month before you make a single call. A small business with 5 channels paying $20 each spends $100/mo on trunk fees alone. With IPComms, that $100 goes toward actual calls instead.

Call Centers & High Volume

No channel limits means you scale without penalty. Call centers running 50+ concurrent calls save thousands per month by eliminating per-channel fees. Add E911, encryption, and failover at no extra cost.

MSPs & IT Consultants

Managed service providers use IPComms to offer SIP trunking to clients without the overhead of per-channel licensing. Simple per-minute billing makes cost allocation straightforward across multiple customers.

Free SIP Trunk FAQ

Is IPComms SIP trunking really free?

Yes. The SIP trunk itself costs $0. There are no channel fees, no setup fees, and no contracts. You only pay for phone numbers (starting at $1.50/mo for a local DID) and per-minute usage ($0.010/min outbound, $0.009/min inbound).

What is the difference between IPComms and other free SIP trunk providers?

Most "free" offers are either community trunks with severe limits (300–500 min/mo, no encryption, no support) or temporary trials that convert to expensive per-channel pricing. IPComms is a commercial provider that permanently does not charge trunk fees. You get enterprise-grade infrastructure, TLS/SRTP, E911, and real support from day one.

Do I need a credit card to sign up?

No. You can create your account without a credit card. Add funds when you are ready to provision a phone number and start making calls.

How many concurrent channels can I use?

Unlimited. IPComms does not charge per-channel fees or impose artificial channel limits. Use as many simultaneous calls as your PBX infrastructure supports.

Does it work with Asterisk, FreePBX, and 3CX?

Yes. IPComms uses standard SIP protocol and works with any SIP-compatible system including Asterisk, FreePBX, 3CX, FreeSWITCH, FusionPBX, Yeastar, Cisco CUBE, Microsoft Teams, and more. We provide platform-specific setup guides.

Is a free SIP trunk secure?

With IPComms, yes. Unlike community or hobby-grade free trunks, IPComms supports TLS for signaling encryption and SRTP for media encryption. The platform includes fraud monitoring, IP-based authentication, and runs on geo-redundant infrastructure across multiple data centers.

Can I port my existing phone numbers?

Yes. IPComms supports number porting for local DIDs and toll-free numbers from any carrier. Porting is free — you only pay the standard monthly DID fee once the port completes.

How much does a free SIP trunk actually cost per month?

It depends entirely on usage. A small business making 1,000 minutes of outbound calls per month with one local DID pays approximately $11.50/mo total: $1.50 for the phone number plus $10.00 for usage. There are no trunk fees, channel fees, or minimum commitments on top of that.
