sip trunking faqWe get the opportunity to talk to people about SIP trunking every day. Some of our customers are very experienced telecommunication technology professionals, but many are just regular business people who want to improve their business communications and save money. We’ve compiled a list of the questions we are most frequently asked about SIP trunking by novices and pros alike.

What is SIP Trunking?

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).

What are the benefits of SIP?

While there are many benefits of SIP, the primary one is reduced communications cost. Most SIP trunking plans eliminate almost all long distance charges in the US. SIP is also sold in a way that is much more flexible and customizable for business. Businesses can purchase only what they need now and easily grow or retract at any time.

What is a SIP Channel?

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.

Is SIP the same thing as VoIP?

Although SIP and VoIP 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.

Do SIP calls sound good?

Good voice quality is essential for any business communication system. With the right solution vendor and configuration in place, SIP calls can be indistinguishable from calls made over traditional telephone lines. It is essential to choose a provider that uses a Tier-1 network. You should also ensure that you have enough internet bandwidth to support the expected number of concurrent calls.

Do I need a technical expert to get started with SIP?

No. SIP.US provides easy to understand set up instructions and a user friendly online control panel for day-to-day management. Our support representatives are also happy to walk you through configuration and get you on your way to enjoying the benefits of SIP trunking.
