Using Your Cable Modem With VoIP

If your business is looking to take advantage of the numerous benefits afforded by modern communications technology, you may be wondering if your existing internet connection is sufficient. While new communications tools and channels provide opportunities to increase productivity and optimize customer experience, high bandwidth is crucial to getting the most out of your voice over internet protocol (VoIP) system.

Many homes and business internet connections are through cable companies. Cable broadband has been available in most markets for the past two decades. This technology is relatively inexpensive as far as cabling and wiring go, as the national network of cable wiring is vast. Many office buildings already have the necessary cable connection, and those that do not are often physically close to the high-speed fiber connections used by cable internet providers. A common question is how to use and optimize cable broadband with a VoIP system. Through a cable modem with VoIP, businesses can easily reap the benefits of high bandwidth internet connectivity.

Cable modem connectivity

Internet service providers (ISPs) deliver connectivity through various means. The highest bandwidth connectivity in many markets is either fiber optic or cable-based. Fiber optic broadband provides faster connection speeds and highest bandwidth, but service is often expensive. Fiber is usually more expensive due to the increased infrastructure costs of bringing fiber to a building. Cable, on the other hand, has a large footprint from decades of growth in the cable television market.

While cable internet might not offer speeds as fast as are available through fiber optics, cable customers can achieve as much as 100 megabits per second (Mbps). These speeds are more than enough for VoIP calling and for supporting advanced unified communications features.

VoIP basics

Businesses are increasingly migrating to VoIP as the preferred backbone for communications. With VoIP, voice data is transmitted using internet protocol, which is a system of prioritizing data traffic over a network. VoIP optimizes network usage to ensure quality calls. VoIP once referred to using internet protocol to connect private branch exchanges (PBXs) to a network carrying voice data. Today, VoIP is synonymous with IP telephony, which involves a host of communications technologies. With IP telephony, packet switched connections are used to exchange voice, fax and other data.

There are numerous benefits of using VoIP or IP telephony, including lower cost and scalability, especially when VoIP is part of a cloud-based unified communications solution. Connecting a VoIP system to the internet is relatively straightforward. It is, however, crucial to make sure you have the right equipment for optimal connectivity. The most crucial piece of equipment is your cable modem or router.

Using the right cable modem

If you plan on deploying VoIP in your organization, you should consider what equipment you will use. VoIP systems can operate with specialized desk VoIP phones that integrate unified communications options. Vendors, such as 8x8, also offer a variety of cordless and conference phones as well as adaptors so that analog phones can work with VoIP technology.

When using a cable modem with VoIP, the main concern is having the necessary ports for voice. Cable modems often double as a WIFI router and might have a handful of ethernet plugs in addition to a connection for coax cable — which is the standard cable wire. Since today many people use cable internet primarily for browsing, applications and other non-voice technologies, some cable modems lack phone jacks. One common mistake businesses make is that they buy a cable modem that does not support phone connections. Check with your internet service provider to ensure that your modem or router equipment should have appropriate phone ports.

8x8's VoIP and unified communications solutions work with a variety of hardware options. Through its virtual office mobile application, softphone capabilities and analog equipment adaptors, desk phone equipment is not necessarily a crucial consideration. In order to be able to use your cable modem with VoIP, however, it is essential to have a router or modem that supports phone input. Before acquiring new equipment, reach out to your internet service provider and a VoIP provider, such as 8x8, to ensure that your office has all the tools necessary for VoIP deployment.

When it comes to VoIP, 8x8 provides a reliable and compliant cloud solution at a demanding level rarely seen by other cloud providers. Don't take your chances with a subpar cloud-based telecom system. Call 1-866-879-8647 or fill out an online form to request a no-obligation quote from an 8x8 product specialist.
