DHCP Issues

I am having some issues with DHCP and Sip Phones.  My DHCP server is on the Endian Firewall.  The problem is endian stops giving IP's to my sip phones for some weird reason, with Windows machines on the network, I can easily just restart the computer and everything works fine again, but when I restart my SIP phone, it doesn't get an IP.

I have seen this multiple times with the Endian DHCP, has anyone else faced this issue?  I have set the lease time on the DHCP server to be a long time, so in reality the lease should not expire and all devices should get the same IP whenever they connect to the system.  There is about 150 IP address that are available, but the sip phones just don't get an IP. 

Are there issues with the DHCP on the endian firewall?  Do I need to manually change anything in the configuration files?

You can try sniffing traffic with Wireshark to find out the difference between windows workstations and sip phones.
