Firewalls</DIV>
<DIV><BR></DIV>
<DIV> We are upgrading to from 4.1.3 to 6.1.1 this month. I have a couple
of hundred phones behind SCCP aware non-Cisco firewalls. Has anything
changed that may cause these phones not to register or operate correctly once
we upgrade?</DIV>
<DIV> </DIV>
<DIV>Thanks!</DIV>
