Multiple User on Operator
ability to setup the SMS messaging on the operator so they can assist different users to get SMS from the Company's Main Number.

We had to implement a very impractical solution to ensure that, should our usual SMS/Fax operator is out of office, that we are still able to send/receive texts & faxes in a timely manner. Requiring a super admin to manually change the SMS/Fax operator whenever the usual operator is out of office is impractical and, at times, impossible depending on the availability of the super admins. For the organization I work for, not having access to (often critical) texts & faxes can result in severe repercussions.
Having multiple users able to send/receive texts & faxes to/from our main company number/fax number would resolve significant issues in a more direct and practical manner. Finding a workaround took several hours, and even still the solution we found is far from ideal.
