FAQs

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.

SIP trunks are cost-effective because they eliminate the need for expensive POTS or PRI lines. You benefit from lower per-minute calling rates, even on metered plans, and free calls between employees and offices, regardless of location. By switching to SIP, your business can save up to 50% on current expenses.

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.

SIP calls can offer excellent voice quality, comparable to traditional telephone lines, with the right vendor and configuration. Choosing a provider like Five9SIP, which uses a Tier-1 network, and ensuring sufficient internet bandwidth for concurrent calls are key factors.

SIP trunking delivers telephone and unified communications services over the internet using a SIP-enabled PBX (private branch exchange). SIP, or Session Initiation Protocol, is the protocol for signaling and controlling multimedia communication sessions, replacing traditional telephone lines or PRIs.

While there are many great benefits of SIP, the primary benefit is reducing your communications expenses. Most SIP trunking plans eliminate almost all long distance charges within the United States. SIP trunking is also sold in a way that can be custom tailored and much more flexible for your business. Businesses can purchase only what they currently need now and easily scale its growth or downsize at any time.
