RE: [Serdev] NAT traversal for RTP stream

Hi Linda!

Have you tried to use the SER "mediaproxy" module instead of "nathelper"?
This is an alternative implementaion for SER to overcome NAT problems, and 
it can handle more than one media line in an SDP. I use it mostly for 
audio/video sessions and it works just fine.

cheers,
  Bernie

RFC 3857 - Is "all-resources" the only legal string?

Hi all,

RFC 3857 states: 

"However, the Request URI can contain a URI that identifies any set of
subscriptions, including the subscriptions to a larger collection of
resources.  For example, sip:all-resources <at> example.com might be defined
within example.com to refer to all resources."

Is "all-resources" the only string that can be used to indicate a set of
subscriptions, or are there other strings? If so - what are they?

Thanks in advance,

Anat.

RFC 3857 - transient states definition.

Hi all,

RFC 3857 states that in certain cases, watcherinfo notifications SHOULD
NOT be sent for any transient states.

Are there other cases of transient states besides the fetch operation
that is given as an example in the RFC? Is there a definition somewhere
of these transient states?

And also - the RFC states that in the Fetch example, no notifications
will be sent at all because all the states are transient. The meaning is
that no notifications will be sent besides the full state Notify that is
the result of the normal Fetch operation, right?

Thanks in advance,

Anat.

Final response and overload

Hi all,

I am looking for the best non 200  final response a server should return 
in case of overload.

I don't like very muche 500 Server Internal Error because it seems the 
server is out of service, whereas it just refuses some requests because 
the bandwith is limited for licensing reasons.

I'd like to know the best practises in this case.

Thanks in advance,

Cédric.

RFC 3265 Subscribe-Notify Question

Hello Folks,
I am new to the Subscribe/Notify RFC. Have a couple of questions.
1. The id parameter in the Event Header of the Subscribe message is
optional. If a UA sends a SUBSCRIBE within an existing dialog without
the id parameter. It then sends another SUBSCRIBE within the same
dialog without an id parameter. Is the second subscribe considered a
subscribe-refresh of the first subscribe. Or is this a new
subscription within the same dialog.

Or do we match the Event Header along with the id parameter to check
if this is a subscribe-refresh or a new Suscribe?

2. If a notify request fails i.e. the response times out or it gets an
error response, the subscription is removed. Does this also result in
Dialog termination if appropriate ? (i.e no other subscriptions or
INVITE requests prending etc.).

Thank You.

RE: Final response and overload


Hi Cédric,

In case of overload server can return 503(service unavailable) response with Retry-After header
requesting client to retry after the time mentioned in Retry-After header.

RFC 3856 - Missing "Event" header in the example.

Hi All,

I've noticed that in the example message flow in RFC 3856, the 200
response for the SUBSRIBE does not contain "Event:" header.

In the last draft before changing status to RFC
(draft-ietf-simple-presence-10) this header appeared.

Can anyone tell me the reason for this change?

Thanks in advance.

Anat.

Per RFC 3265, the Event header is not present within responses.
