Hi,

I would like to ask your opinion regarding the weird RTO's seen in our Core switch. We have a linux based Call Manager and UCCX directly connected.

Ping scenarios

1.From CISCO coreswitch/switch to Call Manager, UCCX and IP Phone = with RTO
2.From CISCO coreswith/switch to PC or any Windows based server = NO RTO
3. LAN PC to Call Manager, UCCX, IP Phone = NO RTO
