* Hellphone was a 2007 French horror film, but there was no character by that name.
* The "recent episode of Inbetweeners" you're referring to is likely a joke or misunderstanding. The Inbetweeners is a British sitcom that aired from 2008 to 2010 and had no character named Vladimir Consigny.
It's possible you're mixing up information from different sources or perhaps there was a joke you missed.
