FAQs
SIP Trunking
What is SIP trunking?
A SIP trunk is a virtual phone line that uses the Session Initiation Protocol (SIP) to deliver voice and other unified communications services over the internet. It replaces traditional telephone lines or PRIs, allowing businesses to make and receive calls using their existing internet connection.
How does a SIP trunk work?
SIP trunks connect your business phone system (PBX) to the public telephone network through the internet. When a call is placed, SIP initiates the session, routes the call, and manages the connection between endpoints. The result is a high-quality, scalable, and cost-effective way to manage voice communications.
What do companies need to use SIP trunking?
To use SIP trunking, you need three main components:
- A compatible IP PBX or SIP-enabled phone system
- A reliable internet connection
- A SIP trunk provider, like SIPTRUNK, to deliver the service
There’s no need for traditional phone lines or expensive hardware.
What are the benefits of SIP trunking?
SIP trunking offers:
- Lower monthly phone bills compared to legacy systems
- Flexible scaling—add or remove call capacity as needed
- Better disaster recovery with features like automatic failover (such as SIPTRUNK’s superTRUNK solution)
How is call quality managed over SIP trunks?
Call quality depends on your internet bandwidth, network setup, and SIP provider. SIPTRUNK uses Tier-1 networks and provides 24/7 monitoring to ensure consistent, high-quality service.
Can clients keep their existing phone numbers with SIP trunking?
Yes. SIPTRUNK supports number porting so your clients can keep their current phone numbers when switching from a traditional carrier to SIP.
What is the De Minimus tax in SIP trunking, and why is it important for resellers?
The De Minimis tax threshold refers to the minimum amount of telecom tax liability that must be met before taxes are required to be collected or remitted in a given jurisdiction. This matters for SIP trunk resellers because it affects how taxes are calculated on customer invoices, reduces tax complexity for lower-usage customers, and SIPTRUNK’s platform handles these nuances automatically.
SIP and VoIP
What’s the difference between SIP trunking and VoIP?
VoIP (Voice over Internet Protocol) is the technology that transmits voice calls over the internet. SIP trunking is the method used to connect VoIP-enabled phone systems to the public telephone network.
How do SIP trunks enable VoIP calling?
SIP trunks connect your VoIP-enabled PBX or phone system to the internet and the public telephone network. When a user makes a call, SIP initiates and manages the connection.
What is a SIP line?
A SIP line is a single voice channel within a SIP trunk. A SIP trunk is the virtual version of a traditional phone line bundle, allowing for multiple simultaneous calls.
Why should resellers sell SIP lines?
SIP lines are flexible and easy to scale. Resellers can handle more call volume by adding lines without the need for physical changes.
Why is SIP trunking important for VoIP resellers?
SIP trunking is the backbone of business-grade VoIP, allowing resellers to offer reliable, scalable voice services without the complexity of legacy infrastructure.
Can SIP trunks work with hosted or on-premise VoIP systems?
Yes. SIP trunks work with both hosted (cloud-based) VoIP platforms and on-premise IP PBX systems.
What value does SIP trunking add to a VoIP solution?
SIP trunking enables direct connections to the PSTN, reliable call routing, disaster recovery options, and improved scalability, all at lower costs compared to traditional services.
