Dears,

 After selecting services option on the IP Phone, Host no found appears in extension mobility.

Go to  Enterprise Parameters replace the name of Call Manager with IP Address and try

2.12.0.0

Thank you.

Could you please elaborate more as IP address already assigned as shown?

Adding that many ip phones are working normally with services capabilities, but I have a few from the same model that are not working at all and shows " host not found"

erase the security settings from the phones and probably that could solve your issues as this issue is with few phones. Could be due to itl certificates

2.12.0.0

Thanks Nithin. It is solved now.
