Analog Trunks
The vast majority of small businesses (3-16 lines total) subscribe to typical Analog Trunks. These are the phone lines that allow you to make and take calls at your business. The following terms are synonymous and are all used to recap the simple analog trunk.
Local Modem
o Co Trunks (Central Office trunks) – referring to the fact that the line originates at your aid provider’s “central office” or the office closest to you before calls are handed off to your business
o Analog line/trunks – referring to the fact that these lines propagate voice using analog signaling
o Pots line – an acronym that stands for Plain Old Telephone Service
o Copper Line/trunk – referring the corporeal pair of copper wire that is fulfilled, at your business
Essentially, these are the most prevalent type of lines because ‘Ma Bell’ (i.e. At&T/Bell Network) has been around a very long time and the Bell network is well developed across the United States. Analog trunks are tried and true, reliable, and allow ease of access.
Digital Trunks
As a company needs a greater amount of lines, a digital trunk or T1/Pri is often considered. The T1/Pri line is basically a particular circuit that can supply up to 24 channels for voice or data to your business. You could have 24 voice calls over a particular circuit. Dream that – one circuit with 24 conversations! Pretty neat.
When digital circuits originated in the ’60s, the circuit consisted of two pairs of copper wire linked to your business. Just think. If you ordered 24 analog trunks, then at some point 24 pairs of copper wire would have to be linked to your business. That’s not very efficient use of materials if you’re a aid provider. Compacting 24 high capability digital channels on a just two pairs of copper wire is much better. Nowadays, you can order T1/Pri circuits in all kinds of flavors, and most providers offer fractional T1 aid if you don’t need all 24 channels.
Now, what does this mean for you and your business? It typically means that as you add more lines to your company (approaching 24 lines), then at some point T1/Pri aid should be economy than ordering all of those analog trunks.
VoIp Trunks
The VoIp or Voice over Ip trunk is the most recent increasing to the option of company phone line. (Calling a VoIp trunk a “trunk” is positively a misnomer, but we’ll call it a trunk for simplicity’s sake) These types of trunks pass voice over the social internet using a broadband data relationship (i.e cable modem, dsl, T1). Your voice is sampled and broken into data packets that magically trip over the internet. These packets are then re-compiled back into voice so that your called party can hear you.
Unfortunately, this technology has some possible capability of aid (QoS) issues. If you’ve used a VoIp softphone like Skype or Yahoo! Messenger, then you may have already experienced problems like latency, echo, or jitter. Although these problems do exist, the capability of VoIp is getting great and great every day.
You may even be well-known with some of the major residential VoIp providers like Vonage and Packet 8. Your local cable company may even be marketing residential digital phone aid that uses VoIp. For businesses, pure VoIp providers are now marketing Sip trunks. Sip trunks have a particular protocol but still use VoIp to allow you to make phone calls. Many Ip compatible phone systems like the Avaya Ip Office now offer Sip trunk compatibility.
So what’s the big deal with VoIp trunks? Well, the biggest push for these trunks is cost. Because the voice call travels over the social internet, long-distance charges are minimized or not incurred. You’re phone call is bypassing the toll-ridden Bell phone network. Consequently, many businesses are choosing these trunks based on cost alone.
Our buyer base has experienced hit and miss capability and reliability with VoIp trunks. A few have had great service, while the majority have had a collection of problems. A vital portion have removed their VoIp aid altogether and subscribed to analog trunks or fractional T1 service.
Regardless of today’s outcomes, these trunks are definite to stay and evolve into a viable alternative for businesses. But remember, even one day with problematic phone aid could cost your company a year of savings.
