Research-Lab™ VOIP H323 DLL Soft Phone SDK 1.5 for Windows Development

VOIP H323DLL Soft Phone SDK brings H.323 protocol support for ActiveX. With this SDK one can create a simple program to connect and start speaking with anyone with a direct IP Address (provided no NAT Router or Firewall is set) or use the Gateway or the Gatekeeper to connect to /or from PSTN lines. Now VOIP open source projects have made it easier to implement a customized VOIP Solution eliminating costly PSTN lines. Though this implementation might turn out fairly complex, our VOIP Implementation Team at Research-Lab will guide you remotely for the same. 

If you have a good quality Internet connection you can get your phone service delivered to you through your Internet connection instead of from your local phone company. We apply only one time nominal $399 charge for the latest version and Implementation Guidelines all for a download, see the sample below. Please note, this includes a PowerPoint Presentation for the best of H323 Soft Phone Implementation for your home or office.
