I have a couple of devices in VoIP monitor before upgrading to the new IP SLA. Now I have a VoIP Jitter operation that is grey. I can't delete it and I have tried readding it with no change. I have manually removed the SLA config from the router and redone it. The router responds to SNMP with no problems and the call path in the other direction (hub --> spoke) works fine. The path spoke --> hub worked fin (showed green) before the upgrade.
I am not sure what else to look at.
