Hi Mauro,
Which type of calls are being dropped ( IP-IP or PSTN ) ?
How frequently are the calls being dropped?
You should enable detailed callmanager traces on callmanager and capture them for a failed call along with calling and called party information. Steps to enable and capture traces are provided in the following link

7921 phones have only PERMITIONS for internal calls, however, fall to the calls either by ip to ip and ip to PSTN ....
I'll try with the trace of call manager thanks
