Running CCM 6.1 with one remote branch. The remote branch has it's own ingress voice gateway. All phones at the remote branch connects to one 4506 switch. We have a Voice recording solution in place recording via spanning a port on the switch.
Problem is that the voice recording quality is not great via this method. At first we thought it might be the Voice recorder but last week we did the following tests:
1.Connect laptop to same spanned port, captured packets and saved them. Playback was not great (same result as with Voice recorder).
2. Connect laptop to IP Phone (span the phone port to the PC), capture packets and saved them. Playback of this was perfect.
monitor session 1 source vlan 100

Anyone seen anything like this or have some pointers?
