Telephone system:Cisco phone deployment

From Hackerspace ACKspace
(Redirected from Cisco phone deployment)
Jump to: navigation, search

Most settings are taken from Xopr's Asus WL500g running OpenWRT kamikaze RC6 with pivot-rooted USB drive and OpenVPN tunnel. (there's not enough room to host the firmware's on the flash ;)


  • copy the settings from the ACKspace setup
  • try and see if the firmware loading works (I.E. load sip from sccp and vice versa)
  • figure out the loading order of images and config files

stuff to know

  • tested with a lot of factory default resets because firmware and/or configs seem to cache unpredictable
  • not clear how to enable logging on atftpd for OpenWRT, either as --no-daemon or writing to log files
  • atftpd on OpenWRT sometimes seemed to crash (testing sccp), resulting in the following behaviour:
    • for sip: 'Requesting Configuration' (seems to boot with cached settings)
    • for sccp: 'Configuring CM List' (seems to boot with cached settings)
    • for factory default: 'Phone Unprovisioned' / UNPROVISIONED
  • couldn't manage to factory reset the 7905 and 7910



small part in /etc/dnsmasq.conf


Note: when setting the TFT server using command line parameters, don't use extra (escaped) quotes: small part in /etc/init.d/S50dnsmasq (uncomment the args to enable the config file mentioned above

args="-K -F $START,$END,$NETMASK,${lease:-12h} --dhcp-option=66,${ipaddr} --dhcp-option=150,${ipaddr}"



cat /etc/init.d/S55atftpd
/usr/sbin/atftpd --daemon --port 69 --tftpd-timeout 300 --retry-timeout 5 --mcast-port 1758 --mcast-addr --mcast-ttl 1 --maxthread 100

Cisco CP-7900 configuration

Setting up configuration files can be done by using the script. It uses both SEP.cnf.xml and SIP.cnf template files to create config files that can either set up SIP or SCCP.
