it is not the only one. You can detect such ghost calls also at
signalling level (via SST).
But detection at media level:
- is the most accurate as time error
- it adds the biggest load on the system (as you need to put all RTP
streams on your servers).
So, which one to use (signalling versus media), is about making a
compromise between accuracy and load (considering that such ghost calls
are corner cases).
