We have been having issues getting our Soundpoint IP 321 phones to contact the provisioning server over the internet. At first I was thinking that our firewall was blocking the traffic, but after messing around with a bunch of stuff it looks like the phone is not getting DHCP in a timely manner , and therefore does not try to contact FTP server during boot. When I static my phones ip address, and then reboot it by power cycling it will reboot, and then when it comes up it will reboot itself, and pull down my config. On a factory phone without DHCP set my phone boots like this: Loading Application - Running "Unknown" - The welcome screen with some details - Then is is on the main phone screen, but shows Network is down. After a few seconds it grabs an ip address, and I am able to ping the phone. But i think this is after it already tried contact provisioning server so it didn't get anything.
Is there something on the phone I can change to have it try for longer? I have tried upping the File TX tries, and Retry wait, but that did nothing.
