Voice over IP in mobile phones will, finally, replace other protocols. A worldwide arena for mobile voice worth about 700 billion $ is up for grabs. Nevertheless, it results complex to guess when this could take place given the numerous obstacles and barriers VOIP may have to rise above. Conventional mobile operators are interested in preventing or postponing this modification from happening.
End to end mobile phone Voice over IP applications consent to two or more users to do a voice conversation directly, without requiring to go through a conventional voice service at any point. They include applications such as: Fring, Gizmo5, Google Talk, JAJAH, Jaxtr, Mig33, Nimbuzz, Skype, Talkety, Talkonaut, Truphone, Vopium, Yackie Mobile, Yahoo! Voice and Yeigo. These applications work via WIFI as well as via mobile network protocols such as GPRS, UMTS, etc.. They are the main menace to established mobile voice carriers.
Conventional mobile operators deal with this threat by diverse ways including avoidance, pressure, lobbying among others.
1. Mobile operators often block VOIP traffic on their own GPRS, UMTS, among others networks.
2. Mobile operators often exclude VOIP numbers in the flat plans or else they inhibit to dial through to them.
3. Habitually, mobile operators pressure handset vendors not to release WIFI enabled terminals.
4. Regularly, mobile operators pressure handset vendors to stop any mobile VoIP access for third party developers in their mobile application developer platforms.
5. All providers of OS for mobile terminals are considering VOIP a prohibited thing.
The checks imposed by usual mobile operators may become an occasion for beginners to the mobile telephony arena. WIFI may become the main protocol for VOIP. Any provider or conglomerate of providers supplying plentyample WIFI coverage, especially in major urban areas, may have an advantage in this new VOIP arena. The source of revenue may realocate from the voice service itself to assured QoS and/or coverage.
Also, at a time when traditional handheld OSs, such as Synbian, Windows Mobile and Leopard, pay too much of a tribute to the war on VOIP, other Operating Systems may take over the space they left in danger, such as Linux in a lot of of its versions.
