data transfer using dial-up

i have a distributed system. From where i have to bring all data to one database. All most all database is in oracle 10g and winxp. Now, the only way to transfer data is using dial-up. So, what should i do to transfer the data in reliable ways.

Should i configure any gateway server or what else. Any help in this would be highly appreciable...
any links would also be helpful..

thanks in advance.
