I've been experiencing a major issue with our company phone number. We use Microsoft Teams to host our main line, which is set up as a call queue for five users on a round-robin basis. No one has the ability to make outbound calls from this number, so imagine my surprise when we started receiving an overwhelming number of calls from people saying they missed a call from us. Since we don't have that number configured for outbound calls, it seems like we may be victims of a malicious spoofing attack. I have a high priority ticket with Microsoft, but they've informed me that it's not something they can help with and that it's an issue with whoever is spoofing the number. I'm considering reaching out to Lumen, since the number was ported from them. In the meantime, we're sending all calls to voicemail to minimize disruption, but this can't be a long-term solution. Has anyone else dealt with similar issues, or do you have any suggestions on what steps to take next?

It sounds like your number is being spoofed, which is a common issue. A lot of scammers use this technique to make it appear as if they're calling from a legitimate source. You might want to put a voicemail message informing callers that your number is being spoofed, and advise them not to give out any information if they receive suspicious calls. Caller ID spoofing is usually temporary, so it might not be a long-term issue.
Yeah, spoofing is a real pain, and unfortunately, there’s not much you can do about it. It's often associated with vishing (voice phishing), and these scammers change their numbers frequently. Getting an incident response expert is a good idea to help manage the calls and minimize confusion for your customers.
It's primarily a spoofing issue, and there’s not a whole lot you can do. Changing your number might be drastic, but if it continues and causes major disruption, it could be worth considering. Also, since you're with Microsoft, they might not be able to assist since this is more about the telecom aspect, not just your VoIP setup.
Unfortunately, spoofing is really tricky. It’s possible to report it, but the FCC typically has limited capabilities when it comes to taking real action. Keep your voicemail updated and just try to ride it out until the scammers move on. Educating your callers when they reach out can also help cut down on confusion.
I appreciate the insight! Keeping everyone informed is definitely a priority.
Just so you know, this happens a lot. It might seem like there's a compromise, but trust me, it's not. It's just an issue with the way the telephone system works. You've got a couple of options: you can wait it out, which is usually the best course, or consider changing your number if it gets too disruptive. Just make sure to keep your clients informed!
Thanks for the reassurance! That's good to know it’s not a breach.
Thanks for the advice! That's what I'm leaning towards doing.
