HUGE Latency Issue

[du365]

Hello all,

I have a client who is experencing 1-2 second phone delay both ways....basically whenever the client send or receives a call...there is a 2 second delay (max) before both parties can begin talking.

We thought that it was a VLAN issue but we ruled that out....I'm at my wits end.

There is something that we find strange when looking at the show int on the router...e0/1 has more errors than s0/0 particularly the collision and interface resets which look larger than normal and continue to increment.

See below:

Any help or advice would be greatly appreciated, I'll try or retry anything.

Without complete details of all of the network topology, this would be very difficult to impossible to figure out remotely.
