What are the best practices to configure port mirroring Passive Recording for SIP phone. We know that a stack switch supports only up to 8 source ports to a destination port. What should I do when you have a stack switch and passive recording is required?

Julian,

This is going to depend upon your recording application but the best way may be to just port mirror the up link port(Unless it is a LAG(2 0r more ports).
The recorder will "sniff" for signaling and RTP (Real Time Protocol) packets that have the identifying information contained in the headers of the packets is designated to record.
I hope this helps.
