H323 to MGCP Fax Issue

I am having issues getting a fax machine connected to an FXS port configured with H323 to successfully fax directly to another Fax machine connected to a VG224 using MGCP. If you dial externally, it connects correctly and faxes correctly. If dialing internally it connects but does not negotiate correctly. Attached is a sample of the dial-peers. The H323 site can fax outbound to an extension (8 digit) but cannot receive inbound 8 digit faxes. I can't find the setting on the MGCP controlled VG 224 to hard code the negotiation speed.

Ensure whether proper QoS setup is there for the WAN and LAN connection between the two routers.Also you may ensure the H.323 configuration at the inbound side.
