SIP Trunking: A Comparison of Connection Types

SIP (Session Initiation Protocol) trunking is becoming very important to many businesses in this modern day and age. In fact, because of the efficiency and simplicity in which it connects different areas of Internet use, speeds up telecommunications, and enhances the entire streaming media experience, it is all but invaluable for online-based companies.

If you are interested in SIP trunking for your organization, it is very important to know about the three main connection types. These types include dedicated line with no traffic, dedicated line with IP traffic, and a public (or Internet) line. These three types of SIP lines are discussed and compared below. The comparison will help you decide which is best for your organization and its particulars needs, preferences, and goals.

Dedicated Line with No Traffic

In SIP trunking, one of the most common options is a dedicated line with no traffic. In many cases this is known as a leased line. The biggest difference between a dedicated line with no traffic and any of the other two SIP trunking options is that there is no other traffic on the line. These lines are among the most reliable and most secure of all. On the other hand, they are also the most expensive. However, this extra expense comes with even more benefits including the highest call-carrying capacity and the need not to use a VPN.

Dedicated Line with IP Traffic

Because dedicated lines with IP traffic are slightly less expensive than dedicated lines with no traffic but have nearly all of the same benefits, they are a very strong option for many organizations considering SIP trunking or VoIP (find out more about VoIP at GetVoiP), especially organizations considering its use for the very first time. It is quite secure and reliable in its own right but slightly slower due to the fact that other IP traffic can interfere with its smooth operation. A way to counter this is by simply giving VoIP traffic and SIP trunking priority over other traffic. Giving this traffic priority is sometimes called Label Switching (MPLS).

Public

The last type of SIP trunking is public. This kind of trunking is sometimes known as Internet SIP trunking. While it is by far the least expensive option of all, it is also the least secure and the least reliable. It also often has the lowest call-carrying capacity out of the three and requires a VPN at all times. Simply put, it has the least features of any of the different connection types but it is still a strong option for organizations looking to get a basic taste of SIP trunking.

The three SIP trunking types discussed above are the main three that there are. Understanding them and their differences is one of the keys to choosing the one that is the best for you and your organization. The right SIP trunking connection type will help make your business, especially its telecommunications operations, much more effective.

    Why can’t my 2003 desktop connect with the AT&T internet we have? We known as they stated things are connected already. I am so frustrated I am laughing concerning the situation, that’s how frustrated I’m. After I use the web it states “Page Not Found.” Any web site it will that. We’ve AT&T Internet + Dial-Up along with a Modem. Help? So what can I actually do I seem like crying. How do i connect to the web?! So what can I actually do?! Help!

    I understand that you could deliver IP calls via SIP trunking to some regular phone. But I must know apart from delivering the information to another finish point, do you know the variations? I am searching for good definitions of both which make the differentiation somewhat clearer. Thanks ahead of time!

    Hello,

    I presently use PhoneBooth.com in my my business calls.

    Phone booth assigns us a telephone number or DID to ensure that phone callers can dial the dpi and achieve their destination. My minutes presently are extremely much for Phone Booth.

    I’ve my account setup to ensure that all of my amounts are submitted for an outdoors number and that i don’t handle Any calls whatsoever. I personally use this to trace in which the calls are originating from where they’re going.

    I personally use allot of minutes, usually around 100,000 minutes per month because many of these calls are delivered to sales departments.

    I want something which allows me to possess my telephone numbers submitted to the number i’d prefer with limitless calling in an affordable rate. Too a pleasant back-office setup where i’m able to manage my amounts.

    Ive checked out SIP trunking plus some other services but it is just a little confusing.

    Phonebooth at this time is really a Virtual PBX therefore it provides me with a lot more than I want.

    All I want may be the call sending with limitless minutes so i am not billed huge rates. The majority of the services I’ve found are generally pay each minute or very costly limitless calling.

    Any ideas could be great.

    Thanks.

    I’ve got a scenario where I’ve Verizon Fios and wish to separate a Voice over internet protocol (SIP) trunking network from my data network. Right now i’m one router (Linksys WTR610N) to deal with both voice and knowledge and think that certain router gets overstressed. I’ve another identical router and 5 static public IP addresses, but what should i put between your WAN ports from the hubs and my Fios internet feed? Would I personally use a switch or hub to interrupt the main one web connection forwards and backwards hubs?
