Q. How do I configure RSPAN on the edge and core switches to capture the voice traffic.
A: In the Edge switches you configure a SPAN session with VLAN 10 or VLAN 20, respectively, as the source, and a RSPAN VLAN as destination.
Example:
vlan xxx
name RSPAN_VLAN
remote-span
exit
monitor session 1 source interface vlan10|vlan20
monitor session 1 destination remote vlan xxx
In the core you configure the RSPAN VLAN as source and the physical interface to which the Voice Recorder is attached as the destination. Example:
vlan xxx
name RSPAN_VLAN
remote-span
exit
monitor session 1 source remote vlan xxx
monitor session 1 destination interface gig1/1
Make sure that VLANxxx is allowed on the trunk between edge switches and core switch.

Q. Will the voice recored server host port be a trunk port.
A: No. The port will be a SPAN destination port. See http://www.cisco.com/en/US/docs/switches/lan/catalyst3750/software/release/12.2_46_se/configuration/guide/swspan.html#wp1036749 for details.
