Load Remote Phone Book Error!

[cmcannon]

I am experiencing the error "Load Remote Phone Book Error" when I attempt to view my remote phone book hosted on my 3cx pbx. This is affecting my t32g and t38g phones, however, I can view the remote phone book on my T21's. 3CX support has told us to run 38.70.0.221 and 32.70.0.221 for our firmware on the phones yet we still get the error. I have also tried the newest firmware on both the t32g and t38g phones, and still get the error. According to packet captures ran by 3CX the phone is sending the request and the server is replying with the correct information. Any idea why I am only having this issue with the t32g and t38g models?
