IP 331 keeps rebooting

We have two IP 331s that keep rebooting over and over.  They were set up on a VoIP system.  But where the office was located, the internet connection was not that good.  So the CEO has gone back to landlines.   We just go thru installing a new Fortinet 70 system. We are using IP phones so we to eliminate pulling extra wires. Every phone works fine except the Polycom IP 331s.   We have at least 10 of these.  We tried resetting back to default, but now the two we did it on keeps rebooting over and over.  Is says the (mac address)cfg failed.   Then we will another screen will say application failed.   I haven't touch the other 8 because we are scared we might screw those up too.  I hate to get rid of these because they are kind of new.  But the CEO says, if we get new phones, they will be the Talkswitch IP phones.  They went in without a problem.
