Trouble with Zakim bridge

Hi Coralie,

During yesterday's teleconference, people trying to enter the call through
Zakim's bridge in Nice experienced some difficulties (the code was rejected,
or just ignored). We finally made it into the call by using the Bristol
bridge.

Some people reported the same kind of issues the week before (but I could
enter the call via Nice last week, and not this week).

Do you know anything about this ?
Thanks,

Emmanuelle
