[cisco-voip] CallManager 4.1(3) and 7914s....

[Kelemen Zoltan]

I've seen worst ... client stuck with ICS 7750. 7905 phones EoS-d, 7906 
requires 3.3(5) at least, officially anything above 3.3(4) is 
unsupported on the ICS.

So theoretically, if you want to buy any new phone(s), you have to do a 
hardware upgrade of the CallManager too. Just imagine telling a 
customer, that they have to change their PBX if they want to buy more 
phones. (I do understand Cisco that they stop supporting their old 
HW/SW, but I don't agree with making their products backward 
incompatible ... )

I'm not entirely sure of 79[46]X support on ICS and 79[46]0 
availability, but this particular client was after the cheapest Cisco 
phones anyway ...

regards,
  Zoltan

ps. there are ways to cram later CCM releases on the ICS. :D but you 
didn't hear it from me and I've seen nothing, know nothing.
