<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I am currently struggling with what sounds like a one way
voice issue at a remote call manager branch using an h323 gateway and phones
registering to a central cluster at HQ. I looked at all the usual stuff –
clocking on gateway is fine etc etc. The problem is basically the remote cisco attendant
users acting as operators say that sporadically they have a couple of minutes
per day when they answer pstn incoming calls but it sounds silent on the line
and they cannot hear the caller calling in – the phone shows the call as
connected. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I also found a bit of conflicting info on the cisco web site
– cisco say in some places try not to use MTP and not to tick the require
media termination on the gateway config page in CCM unless it is absolutely necessary
for example when using non cisco h323 devices etc. However – in other
docs where they talk about possible one way voice / voice cut through issues
the say tick the require Media Termination if you have these issues. Anyway. I
also started looking at the event viewer on the pub and sub (active ccm) and
noticed a lot of application errors as shown below. One example is loads of the
unregister events at times when I know not that many phones will actually
unregister and the transient connection attempts. Has anyone seen similar things
on CCM 4-2 x <o:p></o:p></span></font></p>
