It’s no secret that cell phones have gotten more and more expensive over the years. Newer and hotter cell phones are being released by mobile service providers every day, and it can be hard to stay on top of the constantly changing technology. Even if you aren’t the type of consumer to pick up a new cell phone every few months to stay in style, cell phones eventually do get old, break down, or need to be upgraded for personal or business purposes. For these reasons, many consumers are turning to refurbished cellular phone to keep their costs low, and still get the technology they crave or depend on.

What Is A Refurbished Cell Phone?

Refurbished cellular phones are cell phones that previously belonged to other people, but were returned after they were used. The phones are restored to a working condition, repairing any damage that may have affected the exterior of the phone, and restoring the phone back to the condition it was in when it was brand new.

While a refurbished cellular phone is not a new phone, it’s pretty close. Buying cellular phones refurbished by manufacturers or third parties can give you the opportunity to purchase a phone in near-new quality at a significantly lower price. It can also be a way to buy a phone that is no longer being manufactured or sold, and that would otherwise be impossible to find.

What Should I Look For?

Refurnished cell phones may be of like-new quality, but they still aren’t new. As such, they should be sold as used. Sometimes mobile providers will try to sell popular models of refurbished cell phones as new because they know that consumers are after these phones, and are willing to pay the price. This is simply unfair, and if you are going to be paying close to the price for a new cell phone for a refurbished, there’s no point in buying a refurbished phone in the first place. Do your research beforehand to ensure that you don’t get a bad deal.

Where Can I Buy Refurbished Cellular Phones?

Refurbished cellular phones are sold by mobile carriers themselves as well as by many third party vendors. This is the best place to search for refurbished cell phones, as these companies are very knowledgeable on the models that they refurbish for sale. Mobile carriers and some third party vendors sometimes offer a warranty on their refurbished phones, so if there are any problems with the phone, you can swap it for another phone or receive a full refund. The advantage of shopping with a third party vendor is that a lot of their refurbished models are also unlocked cellular phone, meaning you will have a much easier time getting the phone activated on your network.

Buying a used cell phone can be a great way to save yourself a lot of cash, and afford the phone you’ve been waiting to own. However, you may find yourself dealing with a few issues, even if you remembered to purchase an unlocked cell phone. Not all mobile service providers are happy to pick up customers who already have their own cell phone - they end up losing a lot of money up front. Cell phones are not cheap, and even though service providers cut their customers a deal when they sign up for a plan at the same time they purchase a phone, they are still losing a couple hundred dollars every time someone comes to their company with their own unlocked cell phone.

Connecting cell phones refurbished by manufacturers or third parties to your current mobile service isn’t too hard, as long as they are willing to cooperate. Most modern cell phones use a technology called a SIM card, which stores all of your cell phone’s information on one small chip. As long as your current cell phone has a SIM card, and your used cell phone has a slot for a SIM card, you can switch your cell phone without your phone company ever knowing. Just put your old SIM card in the used cell phone’s slot, turn it on, and your used cell phone should work seamlessly with your current service.

If you don’t have a SIM card, activating your new phone may take some more time. Call your customer service line and speak to a representative to let them know you want to switch your current service to a new cell phone. They should be able to walk you through the process. Beware that they may try to talk you into purchasing one of their phones - you are not required to, and you should tell them you know this. Point out that you have already purchased one of the readily available refurbished cellular phones, and that they are violating your mobile contract by refusing to provide you service, meaning you can move to a new provider without penalty.

Voip solutions are available from many Voip providers and range from simple vop phones to complex routers and controllers. VoIP is not really a new concept and is now available on the market for many years, it’s no more in testing mode. People don’t know that much about a Voip solutions. What are they, how do they work? Here is some information that can help.

Voip solutions can be classified in three general categories:

• end stations (such as phones),
• and controllers.
• gateways and routers,

Like everything else in the IT domain, every category has a specific function that it performs. And if you combine all the functions you will get a complete VoIP system.

VoIP controllers
VoIP controllers, also called IP PBXs, manage the VoIP network. IP PBX controllers are PC-based, running a standard OS (such as Microsoft Windows, Linux or Sun Solaris, but very different) with additional software to control the VoIP systems. Plus they are performing all the functions of a traditional PBX. These systems can provide APIs to extend vendor-provided or user-written features and functionality.

Hardware and software vop phones
There are two types of vop phones: hardware and software.

• A hardware phone is a physical device, very similar to your common phone; it has a handset, dialpad, etc. The only thing that is different from your ordinary phone is that it connects to an Ethernet network rather than a telephone network. vop phones are built with all the necessary hardware (and software) to digitize your voice (i.e., codecs) as well as setup and make calls (i.e., signaling and transport).
• Software-only phones, or “soft” phones, use the PC’s capabilities to communicate with other PC’s over the Internet, by using the PC’s sound card, CPU and network card as part of the phone’s hardware, and thus, enable a PC to become an IP phone.

VoIP gateway
With so many options available today, gateways are also capable of transcoding (changing the signal from one codec version to another so that the voip device can communicate with the rest of the network). A VoIP gateway is a voip device that connects the VoIP network to your public telephone network (PSTN). For example, a gateway uses G.729 codec, while your PTSN network uses a G.711 codec.

VoIP Routers
Routers are inter-network equipments that help a LAN connect to a WAN; therefore the router’s capability to ensure correctly handled high-priority traffic is very important. Since WAN speeds have generally less bandwidth than a LAN, proper packet queuing and priorization is in order to ensure good voice quality across the path.
