01604 360906

Number Spoofing / VoIP Usage: Scammers and automated telemarketing operations frequently use internet-based phone systems (VoIP) routed through wholesale carriers like Gamma. They can easily "spoof" (fake) caller IDs to display local UK area codes—like Northampton's 01604—to trick you into thinking it's a legitimate domestic call. ​Robocalls and Ping Calls: Numbers like this are often operated by automated dialers testing active phone lines, or running phishing/scam campaigns (such as fake energy refunds, insurance scams, or automated financial prompts). ​The "Gamma" Connection: Because Gamma provides the underlying infrastructure, online lookups trace the number back to them as the network allocation owner, but Gamma has nothing to do with the actual content of the call. ​Community databases tracking 01604 360906 feature complaints from people reporting unexpected, silent, or nuisance calls from it.
