Sir,

We are using huge number of Cisco VoIP phones with Part number PID VID: CP-7821-k9=

Recently we received the same VoIP phones with different part number PID VID: CP-7821-k9++=

Please clarify the below points for our reference please

Is there any difference between two part numbers.

What is the meaning for second Part number CP-7821-k9++=

Thanks and Regards
