We have a phone number that I need several users to have access to in order to send text messages from that number. However, if someone were to call that number - it needs to go to a different set of people. I guess I can handle the second part with call handling settings. How do I achieve the first part?
You implement your own app to share sending text messages, right? In your use case, the best solution might be create a call queue (in old way - see the screenshot) with manger username and password. Assign that shared number to the call queue's direct number.
Then authenticate your app that shares the number with other users to send/receive SMS by the call queue username/password.
Then set your call queue's call handling members as normal.
Enter your E-mail address. We'll send you an e-mail with instructions to reset your password.
