[asterisk-users] A couple of questions for the Mitel gurus(phone-related - not systems)

Nigel,

You cannot upgrade a non-dual mode 5220 to SIP.  

If you are referring to the cable that connects the 5310 to a 5235, that
is a standard CAT5 straight-through cable.

Hi Folks,

Just in case there are any Mitel gurus here:

1) Is it possible to convince a non-dual mode 5220 phone to 'upgrade' to
the
SIP firmware? I have inherited one that's Minet only.

2) I have a 5310 conference unit and 5235 phone in SIP mode, but
someone's
lost the connecting lead. Can anyone recommend anywhere in the UK for a
replacement lead or confirm the pin-out so I can check whether a generic
RJ-RJ lead will work without frying anything.

Thanks

Nigel Kendrick
