Hi Wayne,
yes I can.
I'm implementing a test key of the ETSI. The test key is described:
Ensure that the IUT (Implementation under test: here a proxy) on receipt of an INVITE
request with the Request-URI with a maddr parameter indicating a value the proxy is
responsible for and the request was received using the port and transport indicating,
removes the maddr and any non default port or transport parameter from the request and
forwards the message.
I read the same like you. The test key has a reference to 16.4 but I don't know what I
have to do and the reason is I don't understand what a maddr parameter is doing.
I would be very thankful for help.

Markus,
Can you detail a little more the purpose of using the maddr parameter in the
SIP addressing ?. Section 18.1.1 of RFC3261 touches on the use of maddr in the VIA
header of a request. An example purpose of this would be to send a REGISTER request to
the 'all SIP servers' multicast address 224.0.1.75 - which is also why the RFC
recommends including a TTL of 1 so that the request doesn't propagate outside the
local network.
Conferencing or placing someone on Music on Hold to a a multicast stream is
typically seen with directed IPv4 unicast addressing or DNS entries in the SIP address
header fields and a maddr address in the SDP.

Wayne Davies
Hello everybody,
I have questions about the maddr parameter. I have to write a program which should
have an maddr in the Request-URI. I read the RFC 3261 but it seems that I don't have
an understanding for this.
What is the maddr parameter? Multi-home address or Multicast address? When is a proxy
responsible for a request with a maddr parameter and when not? How looks a RequestURI
with a maddr parameter?
Thank you very much.
Greeting
Markus
