I can't offer any help as to what is causing it, but according to this:

http://networking.ringofsaturn.com/RemoteAccess/isdncausecodes.php

"Cause No. 102 - recovery on timer expiry.
This cause indicates that a procedure has been initiated by the 
expiration of a timer in association with error handling procedures.
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."
