A message sending method and device, and a code stream processing method and device are provided. In the message sending method, a first server acquires and caches a code stream which is the same as a code stream of a second server; the first server acquires an initial position for sending the code stream; and after the second server stops sending the code stream, the first server constructs a message corresponding to the code stream, and sends the message starting from the initial position according to a source Internet Protocol (IP) address of the second server.

A method for synchronously implementing media switch in gateways used for IP FAX is disclosed. The method comprises sending a message for notification of fax event from a media gateway which firstly detects a fax event to the other media gateway of the fax event; implementing a media switch in the media gateway which firstly detects the fax event into fax mode; implementing a media switch in the other media gateway of the fax event into fax mode after receiving said message for notification of fax event. Therefore, the method of the invention overcomes the disadvantages of the related art and more particularly prevents fax failure due to difference of routing for a born network and cross-domain. The IP FAX used by the method of the invention can be applied broadly as the method also improves compatibility and reliability for IP FAX.
