Intelligent Phone

Network service providers are slowly migrating from legacy network to full IP networks. Some service providers already run 100% IP based network with only TDM and SS7 connectivity to service providers that are not IP based. Access devices developers have realized that migration from PSTN to NGN will take some time and as a result have decided to support both networks on a single device. Skype dual phone 3088 is a very good intelligent example of such access devices. With this device the user is able to connect on Skype without using the PC. This is a huge benefit on power saving. All what the user needs is connectivity to Internet. This technology integrates PSTN with Skype. This means the user can receive and dial out both Skype and PSTN calls on the same device. This device also uses the well known DECT technology which allows the user to move around with the phone without being restricted by the cord. Imagine being irrigating the garden while speaking with a Skype user who might be in another country talking free of charge. The other user/ callee can be connected on any Skype device even the computer.
The only shortfall of this device is that it uses Skype proprietary protocol. This means for subscribers toggling between SIP service providers and Skype need a separate device for SIP. This is a disadvantage as VOIP devices do not come very cheap. Currenlty technology options in the market allow urers to choose between SIP+ PSTN and Skype + PSTN integration, based on the calling needs. SIP service providers and Skype charge different tariffs from destination to destination. The user will need to consider tariffs for the destinations of interest before choosing the best technology combination. Both of these devices are quite smart as the subscriber receives and dial out using either VOIP or PSTN number. The other disadvantage of Skype over SIP is that Skype can not terminate calls originating from other networks in destinations where Skype do not have phone numbers. Skype users though can still benefit from reasonable outbound call tariffs which make the source of phone bill. It is still a wise decision to invest on Skype device as Skype destinations where numbers are provided also seem to be growing fast.

DUAL SIM PHONE

In the developed countries, subscribers enjoy the reasonable cellular rates and VOIP services. These services include Skype and other SIP services providers. In the developing countries voice calls remain the best way to communicate. A reasonable person would assume that VOIP is also the cheapest solution to the developing countries. This is supposed to be the case but unfortunately cellular Operators in these countries continue closing the doors for VOIP technologies by increasing the call termination fees. VOIP service providers operating in these countries find it very expensive terminating calls in these countries such that it makes no business sense to sell VOIP services for local callers. Most of the subscribers in these countries use cell phones with most of the calls terminating nationally. The best solution should charge much less than cell phone providers for national calls.. The cellular network operators provide tariff structures that are cheap for peak hour callers and a tarrif structures cheaper for off peak hour callers. The subscriber can only gamble between these two structures by choosing one based on the predicted call times. Cellular service providers make sure that subscribers cant toggle between these tariffs per call, by allowing a change to a different tariff only once a month. Some cellular subscribers have tried purchasing more than one SIM card and keep changing it according to the best tariff plan during the time of call. This has disadvantages of damaging the cell phone as the SIM CARD is taken in and out. The solution to this is a dual SIM cell phone. These cell phones also come with a benefit of TV, with some also supporting Digital TV in areas that have migrated to DTV. Subscribers in the developing countries can significantly reduce their monthly cell phone bills by using this type of a phone. One SIM CARD will be for calling during peak hours, another one for off peak hours. These cell phones even go to an extent of supporting three SIM cards. This can help with subscribers that need two prepaid networks and a contract network. As cellular service providers keep punishing the VOIP service providers, subscribers have to definitely find the alternative saving means. In the next article we will show you with calculations that some subscribers can reduce their bills by a minimum of 45%. For example of these smart cellphones visit
