Most PCs with a sound card and the associated microphone/speaker can use ActiveXPhone.
Now try to call yourself to see if it works.
Q1. My microphone does not seem to work. No one can hear
me. Q2. Vista users get a error at the first time running this AtciveX Due to the Vista security issue, ActiveX can not auto detect and install RTC1.3 for Vista users.
Please, following the DOWNLOAD LINK, download and install manually first! Q3. Web Call cannot recognize my sound card. Your sound card must be full duplex. Q4. The other party can hear me, but I
cannot hear the other party. This is likely firewall problem. Maybe SIP Protocol is
blocked; or non-compatible with MS uPNP; or Intrusion detection system issue. If the problem persists, you are suggested to remove all
Web Call file from your local machine. Then you may click the WebCall link
again to initiate a new downloading. The following file should be removed in
\WINDOWS\Downloaded Program Files or \WINNT\Downloaded Program Files directory. Thank you for using WebCall....
You can use the MS tunning wizard. Access from "Control
Panel->Sound and Audio Device->Voice->Test Hardware... "
