Lets Talk SIP

Step 1:
Understand the term SIP and why it matters.

SIP is an acronym for Session Initiated Protocol but like most telecom labels, once you know what it stands for, it still doesnt make much sense. So lets forget what its called and talk about how it works. SIP comes in many flavors but the two most common forms are SIP Trunking and Hosted SIP. SIP Trunking replaces your telephone service, services like POTS or Plain Old Telephone Service (a.k.a. Analog Lines) and T1 or ISDN-PRI (a.k.a. Digital Lines).

Hosted SIP not only replaces your telephone service but it also replaces your PBX or Key Service Unit (a.k.a. your Switch). With Hosted SIP, the only things you need are the actual telephones (a.k.a. Endpoints).

Step 2:
Understand how SIP is delivered.

Unlike conventional telephone service from a telephone company Central Office (a.k.a. The C.O.), which is generally delivered to your door by wires or fiber optic cable, SIP is delivered via the Internet.

By using a router, you can establish service with any Internet Telephone Service Provider (ITSP) you choose, regardless of their location and connect it to any SIP compatible PBX or SIP Endpoint.

Step 3:
Ask yourself if SIP is right for you.

WHY SIP? Perhaps the best way to approach the subject is to first realize that SIP is here to stay. It WILL one day replace all other forms of voice telecommunication and it will do so within a relatively short period of time. There are several reasons for this migration but the main force that drives this shift is economics. The cost to maintain either overhead or buried cables continues to rise as the infrastructure ages. Other reasons for the transition include having a wider choice of competitive providers to choose from and each with more features than traditional services. Add to this, the availability of inexpensive telephone numbers from all over the world, and you have the answer.

Step 4:
Decide on Hosted SIP or SIP Trunking.

This is probably the easiest decision youll make. Either you want to have the Total Control and Compete Flexibility by owning your own PBX using SIP Trunking or you actually prefer to have another company manage it for you and deliver only the endpoint product - the telephone.

Hosted SIP FAQ

SIP Trunking FAQ

WHEN IS HOSTED SIP A GOOD CHOICE?

Hosted SIP is generally a good choice when few phones are involved at any one location, making the cost of owning a PBX, somewhat prohibitive.

Another candidate for Hosted SIP might be a company comprised of mostly work-at-home employees.

This allows each employee to converse at the same time and all without the cost of a PBX.

If you start out using Hosted SIP Service and you find that your needs change and you want to upgrade to your own PBX, most provider will allow you to convert the service when the time comes. However, its best to get this in writing and we can show you how to do that.

You still have a choice when it comes to the actual telephones - even with Hosted SIP .KX-TD.COM offers the widest selection of SIP endpoints available from a variety of manufacturers including Panasonic. And, we continue to test new ones as they are released.

WHAT ARE SOME BALLPARK PRICES FOR HOSTED SIP?
Quality Hosted SIP service providers either charge:

• By the seat (a.k.a.Endpoint), with little to no usage fees. Typical per seat charges range from $30 per month to $40 per month. Many of the features are sold a la carte. Typical charges for the per minute providers is just under 3 cents inbound and 3 cents outbound with advanced features available again, a la carte or,

• No seat charge but with higher per minute rate for both inbound and outbound calling.

WHEN IS SIP TRUNKING A GOOD CHOICE?

SIP Trunking is generally a good choice whenever there are more phones needed than there are phone lines. For example:

A sales company with 30 telephones yet rarely do they have more than 8 or 10 lines are in use at any one time, or

A large home with 20+ phones but only 1-3 phone lines.

Any home or business (regardless of size or location), that needs an in-house PBX would benefit from SIP Trunking. People choose to own their own PBX for a number of reasons. Some of those reasons are because they prefer to have total control, have frequent configuration changes or they wish to integrate devices such as wireless phones, door phones, fax machines, paging speakers, predictive dialers or TAPI. With an IP compatible PBX, off-premise extensions are easily deployed to anywhere in the world so having multiple locations should not prevent you from using SIP Trunking.

WHAT ARE SOME BALLPARK PRICES FOR SIP TRUNKING?
Quality SIP Trunking providers generally charge by the number of concurrent calls that you can possibly make. These are called CCS or Concurrent Call Sessions. A competitive rate is about $10 per CCS. The math becomes quite simple. A company with a 8 lines should expect to pay just under $80 per month. There are no per seat charges so you can have one phone or a thousand phones and the monthly charge is the same. With SIP Trunking, there are few al a carte features available since the features come from your PBX. Exceptions to that are upstream features like Direct Inward Dialing (a.k.a. DID). Most SIP Trunking providers offer free calling for 48 states, Canada and a few of the islands but the cost per CCS is a bit higher.
