What are VoIP lines and SIP trunking?
Supporting existing phone systems and analog devices with updated technology
VoIP phone lines replace plain old telephone service lines (POTS) used for voice and many analog devices (e.g., fax machines, postage machines, ATMs). POPP supplies lines that provide analog signals to existing equipment and convert those signals to Voice-over IP, using an internet connection to complete calls. For businesses with existing PBX systems, we provide SIP Trunks that allow you to make and receive phone calls over an internet connection. This gives you the flexibility of a modern internet-based phone service without replacing your entire phone system. Your PBX connects to the cloud through reliable, secure SIP trunking.
Need phone lines for your fire alarms or elevators? We can also provide additional battery backup and cellular failover in those instances, too.

Frequently asked questions
Q: What’s the difference between SIP and VoIP?
SIP is the specific protocol (language) that enables VoIP (phone calls) to work over an internet connection.
Q: How do I know whether I need VoIP lines, PRI or SIP trunks?
It all depends on the type of existing phone equipment you have on-site and the type of connection it is designed to use. Give us a call and we can help you figure it out.
Q: Do I need to replace my current PBX?
No, not if you’re happy with it. Our SIP trunking services connect your existing phone system to the internet in order to modernize without a full overhaul. However, if you are looking to upgrade to a new phone system, consider our cloud-hosted phone system.
Q: How many SIP trunks do I need?
It depends on your anticipated call volume. Each SIP trunk allows for one concurrent call. We help determine the right number of call paths for your business.
