The VoIP SIP SDK is an efficient solution for integrating SIP-based phone call features into software applications. It offers extensive customization options to accelerate development of VOIP applications.
One of the standout features of this SDK is its high-performance VoIP conferencing client, which can deliver crystal-clear sound even for users with low or high-bandwidth connections, as well as SIP-compatible devices (both hardware and software). This makes it possible to have worldwide communication over the internet or internal networks while delivering superior voice quality. The SDK also supports DTMF, adaptive silence detection, and adaptive jitter buffer.
The Abto LLC VoIP SIP SDK is based on IETF standards (SIP, STUN, etc.), ensuring compatibility with other standard-based products such as Asterisk and OpenSER. It also comes with dynamically loadable codecs, Registrar support, STUN support, and samples for Delphi, C#, VB, VB.NET, C#, HTML, and JavaScript.
Other features of this SDK include echo cancellation, support for playing audio files, hold/retrieve with sample, recording conversations into WAV, updated Delphi, VB, and HTML samples, extended OnIncomingCall event arguments, call transfer support, and added status code on call reject. There are also unauthorized and trying events for user registration, bug fixes, support for VPNs, and the recognition of Authorization ID and FAX.
In the latest version 3.0.4, users can expect explicit multiline handling, improved configuration handling, enhanced stability, and additional new and updated samples. The help documentation has also been updated to reflect the latest changes. Overall, the Abto LLC VoIP SIP SDK is a robust and flexible tool for software developers seeking to add SIP-based phone call functionality to their applications.
