H323Phone DLL 1.5


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 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.

SDK Features:

  • IP-Address based direct local connectivity within LAN
  • Microsoft NetMeeting Compatible
  • Play and Record Wave File
  • Gateway Specification with/without Login
  • Gatekeeper Specification with/without Login
  • Proxy/Firewall support for Version 2.0 [i.e. for Registered Users]
  • Voice/Ring Volume Adjustment [i.e. for Registered Users]
  • Save a conversation to a wave file [i.e. for Registered Users]
  • Easily Create a Answering Machine
  • Easily Create a Interactive Voice Response
  • Easily Create a Professional Call Center
