Whenever the users are sending an SMS internally using the app and searching for the name of their co-users the extension number of their co-users is also showing so if the sender clicks the extension number it will route them to a different conversation. What we want is to make sure that for SMS if the users search for their co-user name then only the primary number will show. All SMS communications should be using the "Primary number" by default across all apps if it's possible.
