What is SIP? – Garrett Smith
Well, I’ll spare you the technical definition. We’ve written about that before.
To me, SIP is the building block of today’s modern business communications.
Forget the technical mumbo-jumbo for a moment. SIP is literally everywhere.
Think about it.
SIP can be found in messaging applications, saas offerings, even security and surveillance systems. Heck, even online games use SIP for communications!
SIP then, is really just the beginning of a much larger picture. It doesn’t matter whether you’re a dealer, distributor, IT shop, MSP or value added reseller.
Because SIP is more than just voice, when you begin selling one SIP based service, you’re going to put yourself in a position to sell other complementary ones as well. SIP trunking opens the doors for things such as:
- Cloud PBX
- Faxing (yes, people still fax)
- IP Surveillance
- Video Conferencing
Armed with this you can even grow opportunities with your existing customer base. It’s fertile land, ready for you to cultivate and seed.
Whether you’re providing managed services, IT help desking or are still slingin’ key and PBX systems, SIP can provide you with many new opportunities.
So what is SIP?
It’s so many different things. It’s opportunity. It’s a problem solver. It’s a productivity enhancer.
Most importantly, it’s additional revenues.
I guess you could say that it’s a pipeline to new areas of growth.
What is a SIP Trunk? – Peter Radizeski
Do you know what a SIP trunk is?
Today, it isn’t as structured as a copper loop attached to equipment dedicated to delivering dial-tone to the phone system and connecting the customer with the public switched telephone system (PSTN).
Today, a SIP trunk is more than likely a static IP address on a router where VoIP packets are routed to send and receive phones calls. For the most part, gone are the days of a dedicated voice circuit. Much like how your smartphone handles voice, text and Internet, now so too does your IP-PBX. That Internet pipe that is so vital to business operations today is also carrying the voice.
The SIP provider is just connected to the business and its phone system via a virtual path mapped out on the router. The voice traffic transverses the Internet to get to the SIP provider, who then routes your voice call along.
The cable to follow is the cat5 connected to the very busy box at the edge of the LAN (local area network, basically the wires connecting your computers together).
SIP trunking is the fastest growing segment of voice. SIP trunks are how most voice services are delivered, even unified communications. It is a SIP session that delivers advanced VoIP services. A SIP trunk is the connection to your voice provider that carries more than dialtone, including instant messages, multimedia conferences, user presence information, and other real-time communications services.
The cost savings that so many talk about with SIP trunking can be attributed to several factors: converged network (running VoIP over the Internet pipe and eliminating the separate voice circuit); and long distance charges on VoIP are less expensive than on traditional phone lines (and in some instances VoIP is flat fee instead of a metered service).
The best thing about a SIP trunk is that it is the first connection to cloud communications. SIP trunking is the dip in the water for customers before they move beyond premise-based phone systems to the world of cloud communications platforms.
