If you are badly in pursuit of a highly powerful and applicable customizable software sip api technology to quickly
add Session Initiation Protocol based dial and receive phone calls feature in your web pages and applications to make voip chat or etc.,
our IP Phone SDK is the best optimal solution possible to serve your needs.
IP Phone SDK presupposes a softphone Software Development Kit strategy of quickly building Internet Protocol (IP)
softphone to add IP chat features in software application as well as dial and receive phone calls there.
Thus, we may assure you that it results in accelerating the development of SIP compliant softphone with
a fully-customizable user interface and brand name.
SIP activeX control, DTMF, STUN support, IM interface, Adaptive silence detection, Dynamically loadable codecs,
and many others tools and components add to IP Phone SDK Toolkit`s powerful characteristic features.
What`s more, by supporting adaptive silence detection, adaptive jitter buffer and DTMF, worldwide communication
over the internet or intern networks either by speaking becomes possible, as IP softphone ensures superior
voice quality. To the top of that, IP soft phone SDK involves a high performance IP conferencing client
capable of delivering crystal clear sound even for both low and high-bandwidth users, as well as for SIP
compatible devices, such as hardware and software using sip api.
We should point out that the product under consideration is based on IETF standards (SIP, STUN, etc.),
so it should be compatible with other standard based products ( Asterisk, OpenSER and others). Here
we cannot but mention that in case you work through firewall or NAT, using our Voice conversation SDK
is not a problem.
