Help finding VOIP servise that spoofs

[bob_johnson]

So sometime ago there was this app (funcall) on android that let you use their app to call people and use sound effects, the way they verified your phone number was by sending you a OTP, their system was not secure at all and I was able to log in as a phone number that was not mine and call anyone I wanted to using their VOIP services and the recipient of the call would get a call from whatever number I logged into the app with, I called a friend using their own phone number.
Are there any other services similar to this one where I can call anyone I want from any number I want, basically spoof my phone number to whatever I please
