VoIP Phone Systems recommend all businesses dynamic, function-rich telecommunications capabilities once accessible in only to the prime, most expensive systems. sophisticated VoIP solutions enable all employees, whether they are down the entry or a thousand miles away, to respond fast to customers and business opportunities by allowing their phones and computers to integrate into one faultless system.
VoIP and Mobile
Your can link your mobile phone to the internet. With will function with VoIP. It is cheaper than the actual mobile call. You're can connect manually or your can use the calling card. Now a day 800 calling card services such as Net2Phone are already providing this opportunity.
Having automatic ANI programmability with Net2Phone, you can have several different mobile phones and easily use your Net2Phone for international and local calls. Your can call any person at any corner of the world.
Now- a- days the multi-radio mode mobile phones such as GSM/WiFi, CDMA/WiFi and like BT with GSM/Bluetooth are being provided to bridge over into VoIP from a mobile phone.
Now companies like Longboard, Calypso, Kineto Wireless are working on "seamless handover" between cellular and WiFi VoIP networks on the network side with different approaches such as SS7 interconnect nodes to application level mobility using SIP gateways to GSM GW MSCs SIP enabled.
And if you take recent IEEE 802.11 working group activities and the IETF "seamless mobility" WG into account, you will know it is just a matter of time until we will be able to use cheap VoIP from mobile phones.
Motorola, Nokia, SonyEricsson, Alcatel are all working on combined mobile/WiFi phones, HP is just about to release their new iPaq product line with Quad band GSM and WiFi.
You never expect VoIP at mobile costing you jus to make a call lesser than that, even its on-net call. Mobile carriers could choose an ISR which provide low cost (VO) IP service to benefit subscribers, but you need to pay on-net tariff. Landline VoIP could be cheap enough to attract users because it uses fixed line which built long ago and cost users very low to make phone calls. Not mobile which uses limited spectrum. It is better to use calling cards to save money.
Calling internationally from cell phone at a cheap rate
You can call internationally from your cell phone at the rate of simple internet browsing! It is amazing but a fact. That can be possible via VoIP. The cell phone will work though the VoIP.
Now it is no need to go through all the trouble of signing up with a reseller & buying yet another box to plug into your phone line and your cable or dsl modem at home.
You can get one different calling cards with 800 numbers. Which would be used from your cell phone? You will have not to pay any connection charges, by choosing the right calling card. And since calling my home phone or calling 800, uses the same amount of airtime minutes on a cell, it doesn't seem to make much sense to buy another box full of microchips.
