Outsourced Call Centers

The modern justification for caller ID spoofing: overseas call centers in places like the Philippines displaying local numbers. Debate over whether this serves consumers or only benefits companies hiding offshoring, with comparisons to email reply-to address spoofing.

← Back to The Australian Government to Require SMS/MMS Sender ID Registraion

The practice of caller ID spoofing for overseas call centers stems from a legacy phone system built on mutual trust, which now allows companies to present a local face for offshore operations. While some argue this benefits consumers by facilitating cheaper callbacks and identifying legitimate services like banks or hospitals, critics view it as a deceptive tactic used to hide offshoring and prioritize corporate profit over transparency. This tension is further complicated by security concerns, as masking a call's true origin can increase phishing risks and erode public trust in caller identification. Ultimately, the debate highlights a clash between the technical convenience of "grandfathered-in" systems and the modern demand for accountability in global communications.

I used to work at two (UK) telcos. There's a historic reason and a modern reason. The historic reason was, just like the Internet, the international phone network was built on gentlemen agreements by engineers who largely trusted each other. A big national telco is unlikely to attack its peers, so there was little need for safety measures. As smaller telcos came in to the mix via deregulation, that understanding changed - but it was hard to retroactively fit controls. The more modern reason is outsourced call centres. You want outbound calls from your Philippines based staff to show as if they were calling from a local number. When large and reputable entities were doing this it was fine. Just like showing a different reply-to address on an email. If you were designing a modern network, it wouldn't be like this. But international telephony is over a hundred years old and has a huge amount of legacy technology and legal agreements.

> You want outbound calls from your Philippines based staff to show as if they were calling from a local number. The company that has offshored it's support to the Philippines might want that, but I doubt any consumers want that. That shouldn't have happened, but regulation comes (20+ years?) after harmful business profit decisions have been made and implemented. But, thank you for the explanation. I have heard similar explanations before, and it has always sounded to me like a situation where the telcos are able to offer a service for a profit for the customers to hide the origin of their offshore call centres (that mostly nobody wants to speak to anyway). I think I just ranted twice, sorry. Thank you!

The consumers 'want' it because if they get disconnected and try to recall, by spoofing a local number it costs them nothing/little since it's a local number (maybe toll-free?) instead of a lot for an international call. Of course, they might want a local call centre even more, but spoofing a local number for overseas call centres does have a purpose.

This consumer couldn't care less about where the person is actually sitting as long as the tasks are done and the problems solved.

"As long as" does a lot of work here, considering language barriers and (in my experience) generally less knowledge in off-shored centers.

A legitimate company registering an local number, routing its Philippines call centre through it and accountable for outbound calls is not really comparable with a random scammer faking whatever number.

Showing overseas based workers of Microsoft as another company name on caller ID is a phishing risk.

Showing workers of companies other than Microsoft as Microsoft on caller ID is a phishing risk.

> You want outbound calls from your Philippines based staff to show as if they were calling from a local number. This is a valid use case, but I’m a bit surprised that the mechanism isn’t better controlled. Surely a better design would be for an actual local entity to forward the call, possibly with an optimization to allow the voice data to bypass the local entity once the call is connected.

When large and reputable entities were doing this it was fine. Just like showing a different reply-to address on an email. For this particular case, do they really spoof the caller ID on an (expensive) international phone call, or do they actually just re-route via a local phone number?

> You want outbound calls from your Philippines based staff to show as if they were calling from a local number I personally don't? Why would I want that. The companies might want to hide that info but I don't think that's a legitimate use case.

Because it is useful for most people to see that they're receiving a call from their bank, insurance company, hospital, whoever. The hospital's call staff might not be in the same building as the doctor - so showing a familiar number is useful. In an ideal world you would be able to trust that number but, as per the above, that isn't always the case.

It's a solved problem. VoIP plus leased trunk lines by the a telco in the market you want to work at. You are limited to fixed set of numbers and you are "local" in the market you want to work at.

That we can do better now isn't important to why something existed to be grandfathered-in in the first place. Call centres were getting outsourced before e.g. Skype was a twinkle in the eyes of Priit Kasesalu and Jaan Tallinn.
