[0024] Hereinafter, the present invention will be further described in detail based on the drawings and embodiments:
[0025] The invention transfers the call type by extending the MGCP protocol, so that the media gateway can clearly use the G.711 codec service, adjust the DSP parameters correctly, and improve the service quality.
[0026] The present invention extends the local connection option of the MGCP protocol. The local connection option is used in the MGCP protocol to specify connection attributes, such as the connection mode (sendonly, receiveonly, sendreceive, conference...). Add an X-calltype (call type) parameter in the local connection option, the value of this parameter is as follows:
[0027] Fax-----001
[0028] Data (Data)-----002
[0029] Text (Text)-----003
[0030] Fax stands for fax service, Data stands for data service, Text stands for text service. Compared with Data (data) service, Text service can only be used for specified text encoding and decoding (suc...
