FXS on a VG200 - MGCP

I have an IP telephony network with CCM 3.1.3.a - a VG200 for the PRi connection and a VG200 for an FXS connection - all configured using MGCP - when a modem is connected to the FXS , I get a maximum speed of 31k. Are there any configurations to increase the speed - I have configured modem pass-through on both the VG200's.Any advice
