Method __init__ Allocate an RTP receiver, configure alaw/mulaw and RFC 2833 codecs
Method close Stop the receiver.
Method __del__ Undocumented
Method get_rtp_address Return the RTP address and port as a Python-friendly tuple.
Method get_rtcp_address Return the RTCP address and port as a Python-friendly tuple.
Method on_vmprx Internal event handler.
Method get_datafeed Used internally by the switching protocol.
Method media_description Return a media description with all supported codecs.
Method default_sdp Undocumented
Method config_codec Configure a codec.
Method configure Configure the Receiver according to the SDP.

Inherited from RxBase:

Method rx_tdm_connect For Receiver subclasses: connect to a timeslot on its
Method get_module Return a unique identifier for module comparisons.
Method get_switch Return a unique identifier for switch card comparisons.
Method get_timeslot Return the tx timeslot for TDM switch connections.
def __init__(self, controller, card=0, module=0, user_data=None, ts_type=lowlevel.kSMTimeslotTypeALaw, reactor=Reactor): (source)
overrides aculab.rtp.RxBase.__init__

Allocate an RTP receiver, configure alaw/mulaw and RFC 2833 codecs and add its event to the reactor.

Note: the VMPrx is not ready to use until it has called 'vmprx_ready' on its controller.

Controllers must implement:
  • vmprx_ready(vmprx, user_data)
  • vmprx_newssrc(vmprx, address, ssrc, user_data)
  • dtmf(vmprx, digit, user_data).
