[cisco-voip] How does voice recorder works? Do I need RSPAN or ERSPAN?

[Buchanan, James]

Depends on the voice recording product you are using. The newer ones don't require SPAN at all in many cases.

I have a setup with 2 DC . There's couple of voice gateway and cucm in each DC.

There's a couple of distribution switches as well.

Between 2 DC and distribution switches are all L3.

Today, my requirement is only to span a few ports connected to the access switches of distribution switch "A". If I do a rspan from those IP phones back to distribution switch "A" and I will connect the voice recorder to distribution switch "A", will it work?

Is it neccessary for me to span the traffic from cucm and voice gateway as well? If so, ERSPAN is required.
