[Asterisk-Users] 3com NBX phones

[Clif Jones]

The IR device is a 3rd-party piece of hardware from Extended System (now 
owned by
iFoundry).  The SIP phone looks like all of the other 3com IP phones 
that I have seen
and turning it over with the front of the phone facing up the connectors 
go from left to
right as follows:
1. Handset connector
2. IRDA (serial) RJ-45 connector
3. PC Ethernet RJ-45 connector
4. Wall Ethernet RJ-45 connector
5. Power adapter

Maybe this will help in comparing the units.  I have posted my last SIP 
firmware
(with appropriate disclaimers) to the list but it is held up in 
moderator no man's land.
