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.
