CIsco SPA509g fails to provision after edditing Expansion Module BLFs

After editing Expansion Module BLFs in the end point manager, all the phones in the system including those without expansion modules fail to provision after a endpoint reset.

this is unlikely, look at tftp requests (google tftp log monitoring) it is unlikely that the edits in the endpointman caused this problem. i use the same phone with expansion, no problems on edit. do you use option 66 in your DHCP to assign provisioning server? was everything tested to be working prior to the BLF edits? can you post the BLF section of the provisioning file(s) (edited for sensitive material)
