We have configured and are successfully utilizing OpsGenie for multiple client accounts for our Support department. Recently, however, we have received what appears to have been a couple wrong number calls from non-client callers. For the live call that was received the caller only spoke Spanish, and our on-call agent did not. As such, we were unable to discern how the caller got the OpsGenie number. Again, we assume it was just a misdialed number.
To avoid this scenario in the future, I am planning to ask each of our clients for their phone numbers so that we can whitelist those specific numbers in the tool; all other calls would be blacklisted. That isn’t an ideal solution, since A) I’d rather allow our clients to not have to share their phone numbers for privacy purposes, and B) a legitimate client might need to place an OpsGenie call from a number outside of the whitelist, so I thought that I would first pose the question to the OpsGenie Community to see if there are any alternative recommendations/configurations.
