Alcatel Unleashed

Hi, I have an old Alcatel Lucent IP Touch with Telnet access. Can I connect this telephone to a sip PBX? I thought of a Fritzbox for example. I know these plans are a little hacky and I don't want to use this setup in production, just for a little testing and playing. Greetings jonjon0815

wich ALE IPtouch phoen do you have ?
40x8 series or 80x8 series
40x8 need to be Extended Edition to work as sip extension or device
