    I know Cisco must have a way to do this, any input would be great!

    Hi,
    I work for an ISP and we're starting to deploy CISCO IP phones (7940).
    We've been using Polycom 300/500/600 phones which use FTP so it's
    simple to create various user config-directories in a single server.
    Now these Cisco phones use TFTP, how can I separate configs for
    different customers on a same server?
    Any pointers would be greatly appreciated.
    Thanks,

    7940 cisco phones request a different file per phone, based on the MAC
    address. If you setup a TFTP server, and you look at the logs you will
    see something like:

    ul 21 18:40:58 embrace in.tftpd[1594]: RRQ from 10.103.188.20 filename
    CTLSEP0011BB0DE63F.tlv

    XMLDefault.cnf.xml
    Jul 21 18:40:58 embrace in.tftpd[1598]: sending NAK (1, File not found)

    to 10.103.188.20
    Jul 21 18:40:58 embrace in.tftpd[1599]: RRQ from 10.103.188.20 filename

    SIPDefault.cnf


    My configuration for each phone is the same, since I have a very basic
    setup. The last resort for the phone is "SIPDefault.cnf", which
    contains
    my phone configuration. But eg for phone 1 I could create a file
    SIP0011BB0DE63F.cnf which contains the configuration for the phone with

    MAC address 00:11:bb:0d:e6:3f.


    The only way I can think of to do this on a per customer basis is to
    symlink configuration files.

    My only problem is the SIPDefault.cnf because some customers use an
    outbound proxy and some don't. When phones at different locations
    reboot "they all look for the same SIPDefault.cnf file" and all hell
    will break loose. At the moment we're blocking outbound tftp on the
    router but that's not very practical. Is there a way to rename the file

    on the phone, so that it requests ex. sipdefault1.cnf?
    I know there has to be a way,
    Thanks
