Accelerate your
custom solution deployment
Enterprises, operators, and solution vendors can leverage the CounterPath VoIP Softphone SDK to accelerate integration of voice over IP (VoIP), video and messaging into their own applications for desktop and mobile devices. Using a single, common SDK with multiple programming wrappers, developers can leverage the same core set of methods and parameters – getting their application to market sooner.
Reliable, superior,
secure communications
When building SIP/IMS compliant applications, engineers can expect excellent voice and audio quality from the SDK through a broad range of Voice Quality Enhancement (VQE) capabilities, such as Acoustic Echo Cancellation, Adaptive Jitter Buffer, Packet Loss Concealment and Noise Reduction. The SDK can also establish secure signaling and encrypted media via TLS and SRTP.
Superior interoperability
The CounterPath VoIP Softphone SDK is compliant with SIP and XMPP standards, and has more certifications than any other SDK on the market. Because its core SDK code is already deployed to millions of endpoints via Bria and X-Lite, you can rest assured that your application will be compatible with the industry's leading IP PBX, SBC and UC platforms.
Rest assured
with extended support
When developing software within tight deadlines, programmers cannot afford to wait for weeks for trouble tickets to be resolved. Our SDK is backed up by the CounterPath SDK Extended Support Plan and provides exclusive access to dedicated Engineering resources, including SLA-based trouble tickets with response time guarantees.
Integrate with any call server or VoIP service
``We evaluated several options over the years, and benchmarked CounterPath as part of our ongoing due diligence process, but no matter where we looked we always found the other solutions to be lacking in multiple areas where CounterPath excelled. We really value being able to pick up the phone and talk to an actual software developer at CounterPath, instead of searching through support forums and message boards.``
