I've a Cisco SPA 502G IP Phone and the handset is broken.
I'm unable to find the part/number of the handset for this phone in the manual, web, etc
But I've found a handset with part/number "cp-handset=" with description "handset replacement for Cisco 7900 series IP phones".
Is CP-HANDSET= compatible with SPA 502G? If not, could you please tell me the correct part/number?
