SIP Phone SDK Introduction
Jphone, developed by Juphoon, is a solution for SIP Phone, which employs a number of technologies originally
created by Juphoon
as Fast ABNF, Object Fsm, RTimer and etc.
JPhone provides various traditional services and Value-Added service which are independent of Call Server
JPhone works with 3G, NGN, P2P, INTERNET and etc.
The JPhone solution allows development and test on Windows.

SIP Phone SDK Audio QoS
QoS requirements on Audio
QoS requirements on network
• Enough network resources• Eliminate physical disturbances
• Support bulk call
• Deny call requests when overloading
• Support emergent calls
• The time gap between the receipt and the
• establishrment of a call is as long as that of
• a callthrough the present PSTN
• Protection from attack and cheat of DoS
• Support the call priority
QoS system for Terminations
• Echo Cancellation(EC)
• Automatic Gain Control(AGC)
• Voice Activity Detection(VAD)
• Packet Loss Concealment(PLC)
• Intelligent code switch
