I have a T1 connection between two locations. Some while ago we started having latency issues with the lines. when I run a ping from the router to the other routher this is the result I get.
Success rate is 100 percent (5/5), round-trip min/avg/max = 8/8/8 ms
SCFU01#ping 192.168.2.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.2.2, timeout is 2 seconds:

The telco company is telling me that the line was tested for over one hour on several occasions and it is clean, but it was working before fine and I did not change anything on the routers. I replaced the Wic t1 cards in both routers and get the same issue. Below are the router configs.

Any help would be really appreciated as I cant figure what the problem is.
