Cisco 7942G With FreePBX CFwALL

hi guys i setup my FreePBX with a Cisco 7942G everything looks good so far but i notice a couple of things

I’m using the last SIP Firmware v9 from CISCO website

  1. the CFwALL button is not working (i mean works but when i put the ext that i want to forward all the calls the phone hang out 3 digit extension)

  2. the other thing is with the TFTP if i change the format of time from D-M-Y to D/M/Y in my SEPMACADDRESS.cfn.xml i don’t see the phone taking that modifications and updating

Any idea guys
