In the end what you want to detect is an actual *loop*, the fact that a
call passes the same phone twice is not, by itself, reason enough to drop a
call. 

How about we check if we've seen 10 redirects, and if we see 10 redirects
(or some configurable number), we drop the call ?

Nobody should transfer the same call 10 times. Or we could take 100. Some
number that doesn't eat too much memory but large enough to make it
unlikely someone would do this themselves.
