[asterisk-users] SIP hardware phones

[Jason W. Parks]

The existing infrastructure I'm speaking of is the existing voice 
infrastructure. It currently supports a digital PBX. No IP whatsoever, 
but the wiring is rated for 10BaseT. As we look to replace the digital 
PBX with VoIP, my options are to abandon that wiring and start using our 
data network, or upgrade our existing voice infrastructure to support 
VoIP. The numbers are showing It would be cost prohibitive to upgrade 
our existing data network to support VoIP.  ...and I think you've just 
supported one of my reasons for continuing to keep voice and data 
networks separate. Since the voice network will be completely and 
physically separate from any non-voice data, and all devices on that 
network are phones, it just became a lot less complicated.  ...and I'm 
only talking 10Mb between the phone and the switch. All switches would 
be interconnected either with 100 or 1000.   Thanks for the response.  Jason
