Inter-tel 6822 phone and asterisk


Has anyone successfully connected an inter-tel 6822 ip phone to asterisk. From inter-tel’s website, it appears to be a SIP phone rather than their own proprietary protocol.

DHCP works, but it complains of not finding an IP card at - does anyone know whether this is a proprietary component of Inter-tel which cannot be got round?

Thanks in advance, any info appreciated
