7912 problem

[amrqura]

I'm working in company that have cisco ip phones 7940's and 7912's.

all of the phones connected to call manager express but the problem is that the phones (7912's) when it open it failed in the (configuring cm list) but 7940's are working well.


Can you know the reason?

does the cme contain a phone load for the 7912 in the tftp?
