Using Aastra phones with Trixbox and Endpoint Manager

Below is a guide for getting Aastra phones up and running with a SysAdminMan Trixbox VPS using Endpoint Manager (You can always configure the phones manually instead of using Endpoint Manager). This guide uses 2 Aastra 55i’s and Trixbox 2.8 CE. This guide could also be used for configuring Endpoint Manager on other distributions.

Firstly you will need to allow access to the TFTP configuration files from your public IP address. You can see how to do this here – http://sysadminman.net/blog/2011/allowing-tftp-access-on-a-sysadminman-trixbox-server-2013

Allowing TFTP access on a SysAdminMan Trixbox server

By default access to UDP port 69, that is used for TFTP, is blocked by iptables (firewall) on SysAdminMan VPS server. This needs opening if you want to use Endpoint Manager to configure your compatible handsets.

When allowing TFTP access we only want to allow fixed IP addresses as there is no security provided by TFTP. You will probably also want to allow NTP (network time protocol) access to allow your Asterisk server to set the correct time on the phone, so we also open port 123.

Run the following commands while logged on as root. Replacing the address (123.123.123.123) with your own public IP address –

# iptables -I INPUT 1 -s 123.123.123.123 -p udp --dport 69 -j ACCEPT

# iptables -I INPUT 1 -s 123.123.123.123 -p udp --dport 123 -j ACCEPT

# service iptables save

Saving firewall rules to /etc/sysconfig/iptables:          [  OK  ]
