font-family:Verdana'>I have following setup configured: Nortel
PBX---E1-->CISCO Router----->CISCO Router (FXO/FXX Port) --- Having
problem of dropping call exactly after 2 minutes and 45 second. Analog set
located at remote site use 9 to access PSTN trunk installed at Nortel PBX and
then it dials out. These calls are dropping after 2 min. 45 seconds...<br>
<br>
The CISCO logs and the Nortel 11C capture shows following error<br>
<strong><b><font face=Verdana><span style='font-family:Verdana'>Cause No. 102 -
recovery on timer expiry.</span></font></b></strong><span
class=apple-converted-space> </span>This cause indicates that a procedure
has been initiated by the expiration of a timer in association with error
handling procedures.<br>
What it means: This is seen in situations where ACO (Alternate Call Offering)
is being used. With this type of call pre-emption, the Telco switch operates a
timer. For example, when an analog call is placed to a Netopia router that has
two B Data Channels in place, the router relinquishes the second channel, but
if it doesn't happen in the time allotted by the switch programming, the call
will not ring through and will be discarded by the switch.<u1:p></u1:p></span></font><o:p></o:p></p>
