Anyone done any packet caputres off a CallManager 5.x or Communications Manager 6.x server?
I am spanning the CallManager server port and can't capture any SKINNY (SCCP for those searching for alternate search terms) packets from the CallManager server. Using Ethereal 0.99.0. Sniffer is plugged into another switch port (not the back of the phone.)
Plugged in a CallManager 4.x to the same SPAN source port and kept the same SPAN configuration and voila--there they all are. Plugged in a CCM 5.x server and no more skinny packets. Same as 6.0.
I did see some MGCP keepalives to/from the voice gateway and saw a COUPLE SKINNY packets from a couple phones that I didn't configure in CCM. (Saw the station alert and registration rejected messages.
I do see RTP from CCM if I put a phone on hold. See TFTP, etc.
Tried a 3750G-24TS switch and a 3524-PWR-XL-EN switch. Same results.
