I haven't gone back to study 3261 specifically about this, but based on
my understanding I think:
The sender of an out of dialog request must ensure that there is no tag
in the To-URI. Depending on where the URI came from it may be necessary
to remove the tag. (When creating new out of dialog t

I have few questions regarding SIP tag parameter used in "From" ,

Hi ,
I have few questions regarding SIP tag parameter used in "From" ,
"To" header fields of SIP
- Does tags define multiple instances of SIP application, using same
user id ?
- How does tags generated ? Rfc 3261 says tags must be GLOBALLY
UNIQUE...what is the meaning of globally unique
If the endpoint is UA, 480 would be a appropriate and if it is server 503 would
be appropriate.

Hi Shrinjay,
In this case only signalling will go through NGN. There would be a media
gateway involved also. Huawei MSC can redirect the call to announcement server
and that server can send SDP in 183 session progress. These SDP parameters will
be used by NGN to connect the media path from An
This can probably happen during Subscribe refresh.

Actually I am not getting when such scenario will occur.
If the Notifier has sent "active" that means it has found matching policy for
the resource. Subscriber would have already created the dialog and if at all

Hello,
In my project, a sip termination may be under certain maintenance testing.
In the process of termination testing, if an incoming call is received, which
response code is more appropriate, 480 or 503?
Since according to 3261, they both seem to be ok.

Manju is correct that transport parameter should not be present in the

Page 151 also suggest that Elements processing URI should ignore any

But I am not sure if the transport parameter in the from header ( w
