Abstract :
Mobile voice over IP (mVoIP) is a tempting prospect for many companies. After all, sending wireless phone calls over IP networks is considerably less expensive than sending them over cellular voice networks. This may become an important service in the coming years as device manufacturers exploit more-powerful processors and cheaper memory. Faster processors and cheaper memory will enable conference calls, voice encryption, the use of compressed codecs, and video calls, assuming there are also fast networks.
