<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>so, in h.323 gw with PRI logs we have " destination out
of order (27)) " for that specific call, and i suppose it is turned back to
callmanager as " unallocated number " and based on it's service
paramter it doesn't stop routing..<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

this issue, to be able to re-route a call when ISDN service is down, but not to
do it when particular subscriber on PSTN is down..<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

have to wait a lot of time to get "busy signal "..<o:p></o:p></span></font></p>
