Welcome to the RingCentral Community

Hi Alexey,

Adding contact is at extension level, which means if you login with the 101 extension, you can only add/edit contact of the 101 extension. In order to add/edit contact for extension 102, you must login with login credentials for the extension 102. This is the same as when you login the https://service.devtest.ringcentral.com with an admin extension (e.g. 101), if you choose the "Admin Portal", you won't see any option for adding user contact at all. Only when you select "My Extension" option, you will be able to add/edit contact for the extension 101.
