<b>To:</b> Cisco VoIP List<br>
<b>Subject:</b> [cisco-voip] How does voice recorder works? Do I need RSPAN or ERSPAN?<o:p></o:p></span></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a setup with 2 DC . There's couple of voice gateway and cucm in each DC.
<br>
<br>
There's a couple of distribution switches as well. <br>
<br>
Between 2 DC and distribution switches are all L3. <br>
<br>
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?
<br>
<br>
Is it neccessary for me to span the traffic from cucm and voice gateway as well? If so, ERSPAN is required.
