Thank you for a quality product. I had a very tight time schedule to convert an existing legacy PC console (softphone) application over to SIP. Thanks to your SDK it looks like I’m going to deliver on time.

What impressed me about Voip SIP SDK was the working demo app that comes with it which has all the common and some more advanced features implemented already so you have a working project on which to base your own adaptation. You can even use the demo app as a good VoIP client without any modification.
The demo is written in an uncomplicated fashion to help show usage of the SDK and good documentation was available where more explanation was needed.
Highly recommended VoIP SIP SDK, fully featured and highly productive.

For us, ABTO provided the best SDK.
The Price is reasonable. Although the function isn’t as completed as some SDK in the Market. But it fit perfectly for our needs.
The setting is simple. It can be implemented into our app in a significantly short time.
But the most importantly, the support team is great, feedback in 24 hrs most times with real solution.
