<p class=MsoNormal><span style='font-size:10.0pt;font-family:Arial'>Recently, I
asked what should happen when an endpoint receives a PROGRESS message
indicating that there are in-band tones and announcements.  Should the T310
timer be stopped?  H.225.0 seems to be silent on this, but it would certainly
seem that it should be stopped.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:10.0pt;font-family:Arial'><o:p> </o:p></span></p>

<p class=MsoNormal><span style='font-size:10.0pt;font-family:Arial'>Should we
stop the timer or should the timer continue to run?  It will expire in short
order (assuming a default value), which suggests the timer ought to be
terminated and T301 started.<o:p></o:p></span></p>

appreciate your input on this.<o:p></o:p></span></p>
