    Feedback
    "Abto has provided Xenex with a robust SIP toolkit that is enabling us to provide extra information to our staff that out VoIP PBX is not able to. It is very easy to use, something that can’t be said for other toolkits, and is giving us lots of other ideas on how to use it to benefit both our staff and our customers. Thanks Abto!"


    "An extremely reliable ActiveX component that allowed us to create seamless and tight integration of our SIP based telephony system with several desktop applications like CRM and Outlook. The component allowed us to complete projects in days that would have taken weeks. The technical support was timely, accurate and extremely helpful."
