I'm seeing an issue with a SPA504g (7.4.6, running G711a) where i get one or more lost packets exactly every five seconds. Sometimes just a single packet is dropped, sometimes ten or more packets are lost and sometimes i get duplicate packets (ie. with same sequence number) The phone is directly connected to a Catalyst3560 from which i set up a mirrorport and save to wireshark. The error counters in the switch are all zeros. I've set up the phone to do debug logging to syslog host but it's not logging anything out of the ordinary.
Anybody have similar experiences? Any tips on how to troubleshoot this further?
