CID-116 It is possible to set a phone number with ID as a caller ID only for group owner

Hello! Can you please tell us more about your issue? Where do you see this error?

Sorry for the confusion that made your question being passed back and forth between the developer and user community.

Since you said that it used to work before, I doubt that there was some change in the phone number assignment in your account. To investigate the issue, someone will need to have a look at your account setting. Since this is a public forum, I would say it's best to submit a dev support ticket to get help.
