10DLC Campaign Failure:Registered numbers sending messages that aren't received
We are an organization of around 100 employees. We submitted a campaign to expand (beyond 49) the total numbers that could send SMS messages to clients. The campaign was approved at the end of February. The relevant steps were followed to join each number to the campaign. But since then the messages from our numbers seem to be blocked. Users can send messages but they aren't always received. This seems to happen most often with clients who have T-Mobile or some of the other smaller carriers. I have an open ticket with Zoom support but seem to be getting nowhere after 6 weeks. Any one else having SMS issues? Getting usefull support?
