An expanding company is deploying leased lines between its main site and two remote sites. Thebandwidth of the leased lines is 128kb/s each，terminated on different serial interfaces on the main router.These links are used for combined VOIP and data traffic.

Users now complain about bad voice quality although no drops areobserved in the low latency queue. What action will likely fix this problem？（）
