The phone originating the transfer sends correctly the

to the publicIPaddress of the NAT", and doesn't pass through the SIP
server (that "manages" the messages for the NATed phones) even if I
configured a dial peer voip matching the voip strings and specifying the
server where I have to send the INVITE requests.
ask cisco to add an outbound proxy configuration option to their gw that
it would use if request uri of a request doesn't belong to itself. they
you could make outbound proxy to point to ser.
