I cannot determine how to connect a CP-7936
inexpensively. I know the router must use Cisco IOS and Cisco Call Manager.
What is an inexpensive router that meets the requirements of the conference
station? What versions of Call Manager & IOS are inexpensive & how do I
buy them, thru Cisco? I no longer have a POTS carrier. Can I route the phone
from router, thru switch then over internet? Somewhere I read about converting
the conference station from skinny to SIP with a firmware upgrade. Would this
be best/cheapest? If so, where and how can I purchase the firmware? How is the
firmware installed into the conference station? Whew, I know the questions are
basic, even laughable. But, I am just now immersed in telephony because of
my naive purchase of the CP-7936. Thank you for your patience and
