The microcircuit of ethernet controler of ip-phone CP-7940 is damaged. Number of microcircuit is
Broadcom BCM5912A2KQMG TG0945 P12 945669 1
Cisco doesn't sell service any more for repair of this phone. We have service center and we can replace this microcircuit but I can't find this microcircuit.
Where I can buy this microcircuit?
