style='font-size:10.0pt;font-family:Arial;color:navy'>It seems that Microsoft
RTC has some problems with originated calls from Asterisk. If I execute Manager
API originate application, with SIP channel as parameter, the Microsoft RTC
softphone will start to ring after a couple of seconds delay, but nothing more
happens after when I answer – there is no second call to an extension.<o:p></o:p></span></font></p>

<p class=MsoNormal dir=LTR><font size=2 color=navy face=Arial><span lang=SL
style='font-size:10.0pt;font-family:Arial;color:navy'>When I looked through the
sip debug, I noticed that Microsoft RTC fails to properly respond to INVITE
messages (I have attached the sip debug). Asterisk has to retransmit INVITE message
for 6 times and even then the RTC still doesn't respond in a proper time.
However, if I do direct call to that problematic Microsoft RTC based softphone,
everything works fine, eventhough very same INVITE messages are being
transmited to it from Asterisk.<o:p></o:p></span></font></p>
