[Partysip-dev] the logic of receiving a 2XX response???

[Roland Zheng]

Hello friends,
  I have figured out how  a incoming SIP request is processed through all the module. but still some
confusion with incoming response. from my understanding according to the code, a incoming response
will be handle by funs like psp_core_cb_rcv2xx, but there is no further process in these functions except wakup stp module. So how all the modules get the incoming response event?  

  another question: could you kindly give me any  logic views about module uap and sfp? what are they
 mainly for?

Thanks,

roland
