Cisco Unified IP Phone 7911G and 6921 replacement models

[SamithMadhukalpa5866]

We are using 7911g and 6921 IP phones and both are now obsoleted.

Couldn't find the exact replacement models for both. Can anyone help me with this?

GO with a 78XX model. You can opt 7811 or 7821. Both phones doesn't have 1G port. if you need a 1G port  you can choose 7841.

Definitely 78xx is appropriate for this. Look at the difference models and select the one(s) that fit your needs.
