    I'm a newby setting up the system. Configured 2 Grandstream GPX-2000 phones. They registered and I was able to place calls from each to the other.
    Problem is that they appear to go to sleep after 3 - 5 minutes and I have to reboot the phones to get them to work again. This is consistent. Also, when this happens there is no indication on the phones' displays that there is anything amiss.

    I would appreciate any advice.

    i have a GXP2000 and i found the same issue... the way i found to work around things was to change the max re-registration time on phone config(to about 41 or 42 days). After that of corse i have to reboot the phone...

    Cheers

    Thanks all for your help. I've discovered that when I turn off the (XP) firewall the phones function properly. I don't understand why the firewall effect would be delayed.

    So, this leads to another question, does anyone know which ports I need to open in the firewall?

    Thanks again for your help.
