Firmware 1.4(5) is available for the 7937. The release notes don't mention your problem, but there are other DHCP fixes in the firmware.

I haven't seen anything like this with our 7937s. Have you Wiresharked the phone, to be 100% sure what the phone is getting via DHCP is what you think it should be getting?

You probably want to try firmware version 1.4.4ES75 which contains the fix for this DHCP bug where the phone does not properly handle DHCP lease times greater than 7 days, https://tools.cisco.com/bugsearch/bug/CSCtr56885.  In order to get this firmware version please open a TAC case and reference this defect.
