SIP vs TDM

What should you use, SIP or TDM, learn why businesses are switching their business telephone systems to something that works over SIP. Some businesses are choosing to stay with traditional TDM telephone systems. Learn more today.

Businesses that are looking to advance or scale their phone systems are facing a tough decision today. The reliable standard for over 3 decades has been TDM (Time-Division Multiplexing). The future is owned by the newer SIP (Session Initiation Protocol) technology. It allows for more innovative implementations and has numerous advantages over TDM systems. SIP telephone systems are becoming the go-to solution as the ISDN switch off looms closer.

Still, TDM is here to stay for the immediate future, until SIP implementations become so cheap that companies no longer have a logical choice but to migrate to the newer technology. This brings up a question we field often about whether companies should stay with TDM, or make the jump to SIP. Did you know that SIP is considered the best telephone system solution

SIP vs. TDM: Which Is Best?

The truth is, deciding which one is better depends on your company. From a technological perspective, SIP is obviously better. There are just so many advantages of treating voice as data, from both a usability and technical standpoint. Did you know that SIP telephone systems make use of both traditional & hosted telephony?

The real question that must be answered is, which one is best for you?

For some companies, sticking with TDM technology may be the best choice. If budgets are low, and if telephone usage is a low priority for your company, sticking with the old technology is a cost-effective, low-maintenance way to go. However, if your phone system is imperative to company success, upgrading to SIP can make a lot of sense over the long term. Just make sure you have enough bandwidth to support adding phone service delivered via SIP to the other traffic you generate over the Internet. SIP is an internet based telephone system.

Advantages of SIP Over TDM

TDM is a relatively old technology, relying on telco switch signaling to make phone calls work. It's a brilliant system, which is why it's been used for more than 50 years. But when it was invented, the Internet wasn't even thought of yet. Now with a hyper-connected world, the ability to transmit data so quickly has introduced exciting alternatives to traditional phone systems.

SIP Costs Less Than TDM

TDM relies on phone lines and technical equipment to make phone calls happen. SIP calls are transferred over a single IP path (or multiple paths if you've engineered some redundancy into your network design!), along with data and video signals. Because everything becomes data, the cost of infrastructure goes way down as you can leverage the same wiring and network equipment for both voice and data traffic. SIP telephone systems are very cost effective for business.

The physical hardware required for SIP is also much less than with TDM as you're using Ethernet rather than specialized Telco interfaces. Gone are the days when you'd need to purchase HSSI cards for a DS-3 that could cost thousands of dollars. SIP doesn't require a specialized, telco gateway nor the installation of phone circuits from the ILEC. Instead, all you need is broadband internet connectivity. Don't let your broadband stop you from switching to SIP telephone system.

SIP Has More Flexibility

Due to a reliance on data transfer, as opposed to physical equipment, SIP has more flexibility, both in implementation and usage. Installing and upgrading SIP trunks is something that can be done quickly and easily without the purchase of expensive new hardware. For instance, if you have 23 PRI lines and want to go to 27 lines, you'll have to order a new card for your PBX and have a second PRI installed. Circuit install can take as long as 30 - 45 days. Turning up more call appearances on an SIP trunk can be done self-serve through a web interface or simply by opening up a ticket with your carrier. A telephone system will work now & when the ISDN switch off commences.

SIP Is Easier to Manage

Because SIP phone service is much like broadband Internet connections, troubleshooting problems becomes a simple process without the need to call in outside technicians to check hardware. IP hardware has a much longer lifespan than TDM, so investments made into the technology bring a higher ROI at a lower price. And, it can be leveraged across both your data and voice networks... as it's been converged into one! Did you know that SIP telephone systems have the largest feature set.

SIP Extends Your Office

Because the signal is controlled like data, phone numbers no longer are determined by the location of equipment. A company headquartered in New York can have a local number for satellite offices in Los Angeles and Dublin. Many providers give you free maintenance on SIP telephone systems.

Phone calls can also be rerouted easily regardless of the location of the receiver. In this way, employees across the globe can interact with phone calls like they were in connecting cubicles. Being able to connect from anywhere, even while on vacation, is another huge advantage of employing SIP technology. Did you know that SIP telephone systems will soon replace PBS telephone systems?

SIP Is More Reliable

There are more advantages to SIP than just cost and features. SIP is more reliable than TDM for a few reasons, mainly the lifespan and operative simplicity of the equipment. But there are redundant backups to ensure your phone system doesn't face any downtime from hardware failures. Make sure you have a telephone system that is reliable & secure, SIP telephone systems give you best of both worlds.

Which Is Best For Your Needs?

Addressing this question again comes down to your needs. If basic phone service is all you need, and your company doesn't have a large reliance on phone service, having a TDM system in place may be the best option. If phone service, and the innovative ways to implement it over IP, is something that can add value to your company, customer service, and business processesFree Articles, you may need to make the leap to SIP.
