Method Details

### __init__(self, host=None, port=5060) (Constructor) Create new instance. Parameters: `host` - our hostname/IP as set in Via headers. `port` - our port as set in Via headers. Overrides: `twisted.protocols.sip.Base.__init__`

### deliverResponse(self, responseMessage) Deliver response. Destination is based on topmost Via header. Overrides: `twisted.protocols.sip.Base.deliverResponse`

### getVia(self) Return value of Via header for this proxy.

### gotResponse(self, message, addr) Called with responses that are addressed at this server.

### handle_request(self, message, addr) Override to define behavior for requests received Parameters: `message` (type=`Message`) `addr` (type=`tuple`) Overrides: `twisted.protocols.sip.Base.handle_request` (inherited documentation)

### handle_request_default(self, message, (srcHost, srcPort)) Default request handler. Default behaviour for OPTIONS and unknown methods for proxies is to forward message on to the client. Since at the moment we are stateless proxy, thats basically everything.

### handle_response(self, message, addr) Default response handler. Overrides: `twisted.protocols.sip.Base.handle_response`

### responseFromRequest(self, code, request) Create a response to a request message. Overrides: `twisted.protocols.sip.Base.responseFromRequest`

Class Variable Details

    ### locator Type: `NoneType` Value:
        None

    ### PORT Type: `int` Value:
        5060
