<p class=MsoNormal>Hello list,<br>
<br>
I have a situation where I am receiving a lot of ISDN 0x66 codes (Recovery on
timer expiry) in my calltracker output from one of our AS5400's. I think
this is indicating to me that the cisco took too long to find an acceptable
destination for the call. Is this correct? If so, is there a way to
tweak the time before the thing gives up? Do we know how many times the
cisco will try to hunt to the next SIP gateway before it gives up and drops the
call?<br>
<br>
The reason why I was thinking it was taking too long is that almost all of
these 0x66 errors have the same symptoms, 0.00 conn time, and a total call time
of an average of 8.5 seconds long. If I'm on the wrong track please let
me know; I'd like to resolve this issue.<br>
