Frequently Asked Questions About SIP Trunking
If your company is growing, a traditional phone system will actually punish you for that. Hiring more people means adding more phone lines.
With a PRI (Primary Rate Interface), you’re using a traditional phone line to make phone calls. Each PRI circuit allows for up to 23 simultaneous calls. If you need more, you have to buy more PRIs in bundles of 23 channels at a time.
Your bill becomes unnecessarily high because you’re paying for a number of channels you don’t need. This type of system doesn’t give you the flexibility or predictability that you need in your recurring or upcoming expenses. And makes scaling particularly difficult if you’re growing your call center.
SIP trunking makes it easy to upgrade to a higher plan at any time. You can add more concurrent calls (also known as SIP channels) and phone numbers in real-time, one or many channels at a time.
Each SIP trunk can support a number of SIP channels. A SIP channel is much like a telephone line. It represents one concurrent incoming or outgoing phone call.
Although VoIP and SIP are sometimes used interchangeably, they are not the same thing. The term VoIP stands for Voice Over Internet Protocol. It is a broad term that covers any phone call made over the Internet. The term encompasses a group of protocol technologies of which SIP is an example. In short, SIP is one of the specific protocols that enable VoIP.
Good voice quality is essential for any business communication system. With the right solution vendor and configuration in place, SIP calls can sound identical to calls made over traditional telephone lines.

SIP trunking is a method of delivering telephone and other unified communications services over the internet. It works with a SIP enabled PBX (private branch exchange). SIP stands for Session Initiation Protocol and it is the communications protocol for signaling and controlling multimedia communication sessions. SIP trunking replaces traditional telephone lines or PRIs (Primary Rate Interface).
