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
monitor session 1 destination interface Fa2/6
Anyone seen anything like this or have some pointers?
I would check to see what Codec is being used. Most recording solutions can only handle G711 and not even G722 (even though it is the same bandwidth....as a matter of fact....did you turn off the G722 advertising?)
It it mostly G711 calls but seeing as this is a callcentre, calls enter at the branch, traverse the WAN to get CVP treatment and then goes back to branch. Obviously using transcoders and MTP resources.
I would suggest try it while spanning a single port (like you did on the phone, but through the switch) and see what that does. It may just be an issue of overloading that one port. You can't get 22 straws into one mouth without a little dribbling.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
