class documentation

A Via is a SIP Via header, representing a segment of the path taken by the request.

See RFC 3261, sections 8.1.1.7, 18.2.2, and 20.42.

Method __init__ Set parameters of this Via header. All arguments correspond to attributes of the same name.
Method rport.setter Base._fixupNAT sets rport directly, so this method sets rportValue based on that.
Method toString Serialize this header for use in a request or response.
Instance Variable branch Unique identifier for this request.
Instance Variable hidden Obsolete in SIP 2.0.
Instance Variable host Hostname or IP for this leg.
Instance Variable maddr The destination multicast address, if any.
Instance Variable otherParams Any other parameters in the header.
Instance Variable port Port used for this leg. @type port int, or None.
Instance Variable received Undocumented
Instance Variable rportRequested Whether to request RFC 3581 client processing or not.
Instance Variable rportValue Servers wishing to honor requests for RFC 3581 processing should set this parameter to the source port the request was received from.
Instance Variable transport Network protocol used for this leg. (Probably either "TCP" or "UDP".)
Instance Variable ttl Time-to-live for requests on multicast paths.
Property rport Returns the rport value expected by the old SIP code.
def __init__(self, host, port=PORT, transport='UDP', ttl=None, hidden=False, received=None, rport=_absent, branch=None, maddr=None, **kw): (source)

Set parameters of this Via header. All arguments correspond to attributes of the same name.

To maintain compatibility with old SIP code, the 'rport' argument is used to determine the values of rportRequested and rportValue. If None, rportRequested is set to True. (The deprecated method for doing this is to pass True.) If an integer, rportValue is set to the given value.

Any arguments not explicitly named here are collected into the otherParams dict.

@rport.setter
def rport(self, newRPort): (source)

Base._fixupNAT sets rport directly, so this method sets rportValue based on that.

Parameters
newRPort:intThe new rport value.
def toString(self): (source)

Serialize this header for use in a request or response.

branch: str = (source)

Unique identifier for this request.

hidden: bool = (source)

Obsolete in SIP 2.0.

host: str = (source)

Hostname or IP for this leg.

maddr: str, or None. = (source)

The destination multicast address, if any.

otherParams: dict = (source)

Any other parameters in the header.

Port used for this leg. @type port int, or None.

received = (source)

Undocumented

rportRequested: bool = (source)

Whether to request RFC 3581 client processing or not.

rportValue: int, or None. = (source)

Servers wishing to honor requests for RFC 3581 processing should set this parameter to the source port the request was received from.

transport: str = (source)

Network protocol used for this leg. (Probably either "TCP" or "UDP".)

ttl: int, or None. = (source)

Time-to-live for requests on multicast paths.

Returns the rport value expected by the old SIP code.
