Abstract
A method and apparatus for determining a media codec in a Session Initiation Protocol (SIP)-based Voice over Internet Protocol (VoIP) network are provided. The method includes determining an SIP entity to be assigned with a priority for determining the media codec, generating an SIP message including information on the SIP entity having the priority for determining the media codec, and transmitting the SIP message.
Claims22
A method of determining a media codec in a Session Initiation Protocol (SIP)-based Voice over Internet Protocol (VoIP) network, the method comprising:
- determining an SIP entity to be assigned with a priority for determining the media codec;
- generating an SIP message including information on the SIP entity having the priority for determining the media codec;
- and
- transmitting the SIP message.
A method of determining a media codec in a Session Initiation Protocol (SIP)-based Voice over Internet Protocol (VoIP), the method comprising:
- receiving an SIP message including information on an SIP entity having a priority for determining the media codec;
- determining a codec to be used according to the SIP entity having the priority for determining the media codec;
- generating another SIP message including information on the determined codec;
- and
- transmitting the other SIP message including the information on the determined codec.
A system for determining a media codec in a Session Initiation Protocol (SIP)-based Voice over Internet Protocol (VoIP), the system comprising:
- a Session Description Protocol (SDP) offerer for determining an SIP entity to be assigned with a priority for determining the media codec, for generating an SIP message including information on the SIP entity having the priority for determining the media codec, and for transmitting the SIP message;
- and
- an SDP answerer for receiving the SIP message including the information on the SIP entity having the priority for determining the media codec, for determining a codec to be used according to the SIP entity having the priority, for generating another SIP message including information on the determined codec, and for transmitting the other SIP message including the information on the determined codec.
