I've worked with ISDN off & on since the mid-90s and have _never_ had to 
do this.  In fact, a standard ISDN troubleshooting step is to disconnect 
the line temporarily (thereby breaking the connection) so that the CPE 
can reestablish Q.921 and re-register its SPIDs.

I've had to call the telco about plenty of other problems but never 
about anything like this.
