Business Phone Line Options
Author: John SheplerEvery business, big or small, needs at least one phone line. Phone lines may look familiar, but you may have more options than you think. Are you sure you have the right phone line for your business?
Normal telephone connectionThe historic telephone line we are all familiar with is the analog telephone line, also known as POTS for private old phone service. This is vanilla.
The symptoms of POTS are as simple as they appear. They consist of a single twisted-pair copper cable that runs from a standard RJ-11 telephone jack on the wall to the telephone company's central office. A telephone conversation is carried out by alternating current in the wires.
You may not know that POTS is an independent telephone system. Phones usually consist of passive electrical components. They got their power from the telephone line... and still can. Even if there is a power outage in your area, you will still have telephone service.
What has happened recently, however, is that even single-line telephones have become electronic and require an AC power source and/or batteries to operate the circuits. This is especially true for wireless phone systems with multiple phones. You can receive a dial tone during a power outage, but you need a backup battery to power the phone, not the line.
Multiple lines
Don't limit yourself to one POTS line. You can have as many as you want. Note that there is no scale effect here. Whether you use one phone per line or use external lines with a switched telephone system or PBX.
Wireless option
Is it possible to completely remove the telephone line? That's what a cell phone is for. The "land line" is no more. Everything is done by cell towers, not wires. Wireless can always work great for freelancers out of the office. With a tariff plan, you can have both Internet and voice telephony on the same device. You can expand your mobile phone settings with free incoming, fax and international calls. Shared plans can support small offices and individual users. Larger jobs still require a fixed connection.

A telephone line consists of several telephone lines connected by a single cable. There used to be analog trunks, but this technology has become digital. The most common trunks are T1, ISDN PRI and SIP.
The T1 lines are designed to replace the various analog POTS lines. Instead of separate wires, T1 lines are multiplexed to divide the available bandwidth into 24 independent channels. Each channel can be considered as a separate telephone line.
What if you already have a dozen phones and want to replace all phone lines with a single T1 line? Chances are you'll get the same or better service for less monthly fees. The field called "Bank of channels" provides switching between T1 channels and analog lines. Connect your phone as usual.
T1 with ISDN PRI
ISDN PRI or Primary Rate Interface is a variant of the T1 line. It uses the same channel allocation scheme but assigns one channel to bind and bind all others. This means that you have a maximum of 23 BOMs in a PRI trunk. The tradeoff is that your phone calls will be faster than ISDN PRI. This is important for call centers and other organizations that require high performance telephony.
Most PBX systems currently have a built-in T1 and ISDN PRI interface scheme. Just plug in the original and the system will do all the necessary conversions.
SIP trunks
Many companies are considering switching to VoIP technology or have already done so. SIP trunks are a natural addition to VoIP phone systems. Their advantage is that they use the same SIP protocol as telephone ones. Remember that VoIP or SIP phones are usually connected to an Ethernet LAN shared by computers, printers, and other network devices. The SIP trunk extends the network and thus connects to the VoIP service provider.
Like T1 and ISDN PRI, SIP trunks support multiple simultaneous telephone conversations. The difference is that these conversations consist of streams of packets combined into one line, rather than splitting the line into separate channels.
Another advantage of SIP trunks is that they can carry Internet traffic just like phone calls. After all, everything is in a package format. It is important to note that the backbone is configured to prioritize voice traffic over data traffic to ensure voice quality. This is called class of service or quality of service.
Which phone line is right for your business? One way to quickly figure this out is to get some competitive pricing on everything from POTS and SIP trunking to business phone lines .
