Can't you just clamp it with zeners or something similar....

First of all you must have a signal transformer, then you only need some zener protection. You can't connect the telephone line directly to the amp becuse the signal is floating and balanced. The result will be a huge hum.

Abey Saaley, kiya kar raha hai phone key saath?

Jacco me thinks this guy is doing something "interesting"... especially if he is between the age group of 15-25 Seen a lot of that. Me also hypothesizes he blew whatever he had working when the tel rang.....
