Gphone Buddy Server SIP VoIP for mobile devices
Voice is the most ubiquitous form of human
communication. Voice calling, voice chat and
voice messaging can be added to networked
PocketPC/WinCE solutions as either a stand-alone
voice application, or as a voice complement to
data applications by the inclusion of
PocketGphone from VL Inc. Current wireless
network growth is coming from networks based on
the 802.11/Wi-Fi standard, which is unregulated
and can be quickly deployed in a very cost
effective manner. Wi-Fi today has a data rate of
11 mbps, enabling a wide array of enterprise and
consumer applications and services including
VoIP. PocketGphone brings full duplex SIP
compliant VoIP to resource-constrained, IP based
mobile consumer electronics devices based on
PocketPC/WinCE. PocketGphone has very low
software latency, requires minimal bandwidth and
supports NAT environments. Gphone Buddy Server
handles address book name to IP matching, user
administration and authentication. Gphone Buddy
Server is the server solution for enterprises
wanting to deploy the power of VoIP for internet,
intranet or IP-VPN environments.
