It depends on how out of sync the clocks are and the type of signaling 
being used.

For a T1 with robbed bit signaling you would just hear a click or pop 
on the line. If the clocks are close this may just occur a few times a 
day. If there is more difference in the clocks it could happen every 
few minutes or more.  For PRI ISDN it may drop the calls or not allow a 
call to be set up. There have been some in the past who have had 
problems getting PRI ISDN to stay up and it was due to clocking.
