We use IP phones and we connect directly to our other office using a T1 line on a cisco 1941 router.  On the one side the sound quality is perfect.  On the other side the sound has a echo.  Is there commands that I can do to eliminate.  

this is what I have
interface Serial0/0/0
ip address
service-module t1 clock source internal
service-module t1 timeslots 1-24

I am using a cisco 1941 with a hwic dsu/csu inteface card.
