sipsimple.msrp.MSRPChat implements instant messaging (IM) over MSRP for the middleware. This class performs the following functions:

  • automatically wraps outgoing messages with Message/CPIM if that's necessary according to accept-types
  • unwraps incoming Message/CPIM messages; for each incoming message, MSRPChatGotMessage is posted
  • plays notification sounds on received/sent message
