Cisco Voice Gateway reports error when adding new gatekeeper

Hello all.

A wierd problem when I try to add a 3rd gatekeeper (with its own zone
and priority) to the Cisco voice gateway. It reports that the
"Gatekeeper already configured". However when I do a show gateway I do
see the 3rd gatekeeper as well but not with the correct priority. (The
first 2 are ok). Now this happens even when I try to change the
priority of the first 2 gatekeepers.

I also tried grabbing the startup config via tftp, modifying the
entries under my fast ethernet interface to include all 3 gatekeepers,
saved and tftp-ed the file back in as startup config and rebooted the
voice gateway. It still does not show the 3rd gatekeeper when i do a
show run, but when I do a show startup all three gatekeepers show up
correctly under fastethernet3/0 with the right priorities ! If I do
copy startup run, it still reports the same "Gatekeeper already
configured".

(Also tried shutting down the fastethernet interface, telnetting via
another interface, added the Gatekeeper and un shut it.. no luck !)

Would really appreciate it if anyone has any ideas as to how I can get
around this (without having to hyperterm into the console ?)

thanks.
