    I have the following message when I connect my phone Polycom IP320 and IP550:
    "could not contact boot server using existing config"
    in my folder / tftpboot I have my firmware and my config MAC.cfg and MACreg.cfg
    is there a username and password for the TFTP?
    Otherwise how to create a user tftp for Polycom

    the only thing that you need to do is to set on your polycom the server settings, choose Trivial FTP and put your Elastix's IP, then on the web interface go to PBX -> Endpoint configuraion, do a scan of your network, select the polycom that you want to configure, select the corect model and assign it an extension. Reboot your polycom, and it will be donwnloading your file from /tftpboot

    Are the phones plugged into your PBX or is another device their gateway?
    If you have a firewall/router serving them DHCP and don't have it telling them where to find the tftp server they may be dying there.

    You can manually set the dhcp server and have them use tftp on the phone by entering setup (default pw for polycom 301/501 is 456).

    If you have a linux machine/etc where you can edit the dhcpd.conf file it would look like this (assuming your pbx is, router is at,etc):

    ddns-update-style ad-hoc;

    option voip-tftp-servers code 150 = ip-address;
    option voip-tftp-servers;

    subnet netmask
    option subnet-mask;
    option domain-name "";
    option routers;
    option domain-name-servers,;
    option ntp-servers,;
    option tftp-server-name "";
    range dynamic-bootp;
    default-lease-time 3600;
    max-lease-time 7200;
