HI,
I have some strange problem on one of my Phone systems.
Sometimes during a call we get Jitter on a server (TCPdump on server). we see a delay in the RTP packets inbetween of 0.1 and 1.1 seconds. What causes a silence moment in a call. There is no packet loss just this strange jitter. The jitter is visible on all the legs so in comming and outgooing. it does not matter if it is a internal call or an external call. All phones are connected directly one the network no NAT or anything only the VoIP trunk is gooing through NAT. the phone system is installed on Proxmox 4.3 (KVM virt) we have multiple phone sytems running on the same server and they dont have this problem. If we start a ping to 8.8.8.8 we dont see the delay jusst a stable ping of about 7ms.
The server has 2 NIC's and about 5 static routes (to reach the diffrent sites) disk and NIC are Virtio based.I hope someone has an idea?
Aron.
