Hi, I use pjsua_vc6.exe can make a single call. But how can I make Multiple call ? When I press "M" and put in like sip:201 at 1.1.1.1,202 at 1.1.1.1 but the program does not like this format. What is the correct format then I can simultaneously make few call please. Thanks in advance, Sen -------------- next part -------------- An HTML attachment was scrubbed...
