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> 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.<o:p></o:p></span></font></p>
