$0.009/min. No Contracts.
Low-cost SIP trunking with no per-channel fees. Connect your Asterisk, FreePBX, 3CX, or Teams PBX in minutes. Inbound and outbound trunks with TLS/SRTP encryption and real human support.
What is SIP Trunking?
SIP trunking replaces traditional phone lines by connecting your PBX to the telephone network over the internet using the Session Initiation Protocol (SIP). Instead of paying for expensive PRI circuits or analog lines, your voice traffic travels over your existing broadband connection — cutting costs by 40–60% while adding flexibility and scalability.
Traditional Phone Lines
Expensive PRI circuits ($300–$800/month), limited channels, long provisioning times, and inflexible capacity. You pay for lines whether you use them or not.

SIP Trunking FAQ
Common questions about SIP trunking and how IPComms works.
SIP trunking is a method of sending voice and other communications over the internet using the Session Initiation Protocol (SIP). It replaces traditional analog phone lines and expensive PRI circuits by connecting your PBX phone system to the public telephone network (PSTN) through a broadband internet connection. This eliminates the need for physical phone lines and typically reduces calling costs by 40–60%.
IPComms SIP trunks are free — there are no per-channel or per-trunk fees. You only pay for usage: outbound calls to the USA/Canada cost $0.010/min, inbound local calls cost $0.009/min, and local DIDs are $1.50/month. There are no contracts and no monthly minimums.
SIP trunking works with any SIP-compatible PBX system including Asterisk, FreePBX, 3CX, Microsoft Teams (Direct Routing), Cisco CUBE/CUCM, Avaya, Genesys Cloud, FreeSWITCH, and most other modern IP-PBX platforms.
VoIP (Voice over Internet Protocol) is the broad technology for making phone calls over the internet. SIP trunking is a specific application of VoIP that connects an on-premises or cloud PBX to the telephone network. Think of VoIP as the umbrella term, and SIP trunking as the bridge between your business phone system and the outside world.
With IPComms, you don't need to worry about trunk counts. Our service has no per-channel fees — you can make as many simultaneous calls as your internet bandwidth supports. A general rule of thumb is that each concurrent call requires about 100 Kbps of bandwidth.
Yes. IPComms supports number porting for local and toll-free numbers across the United States. The porting process typically takes 7–14 business days for local numbers and 5–10 business days for toll-free numbers. You can start using IPComms immediately with new numbers while your existing numbers are being ported.
