I sent back a 622 that would freeze up and reboot. I received another one and it froze up 24 hours later. I disabled the caller ID function and ran for a week with NO reboots. I enabled caller ID and had 2 random reboots within 24 hours. This does not happen everytime the phone rings. I also have 2 dsl filters in series with phone line; No help there. I guess the caller ID 'COMMAND" from my phone line screws up the software in 622. I leave the phone line hooked up ,just caller ID disabled on 622 setup. Is caller ID command digital or analog? Any suggestions for filtering this signal? I have never had phone trouble before with any dish receiver but this is first unit to have a caller ID function. Not a big deal but would like to resolve issue.
