Login to your Exotel account and click on "Co-workers & groups" tab on the left side panel and "Invite Co-workers" button on the top right as shown below:
You can choose to give them User, Supervisor, or Admin access. More information on the access rights is provided here.
A Coworker once added should verify their registered numbers in order to make and receive calls using Exotel. For the verification, please give a missed call from the agent’s phone to the number displayed in the note.
For the new user, the generate password link would be sent out on the email they have registered in it.
Note that the default number of maximum co-workers that can be added is 50 and in case you wish to add more, please reach out to our support team at +918088919888 or write to us at email@example.com and we shall assist you henceforth.
