Sameer,
Understood, but what we're trying to do is document the procedures for
out-of-dialog OPTIONS that is intended to ping the operational status of a
neighboring device. We're not focused on pinging a device that is three SIP
proxy hops away. The purpose of that document is, for example, to a
Hi Paul,
The draft document talks about procedures to check operational status of SIP
elements which support OPTIONS.
In network, there might be some SIP elements which do not support OPTIONS
and they will respond appropriately with 405 (Method Not Allowed) to OPTIONS
ping, proving that they are

UA opens a new TCP connection to the SIP proxy. This TCP connection will use a
new source port (this is normal for TCP). It will go through NAT again, which
will probably assign different public port to this connect
Mustafa,
Not specific to IMS, there is a general need to query for operational
status. Unfortunately, we're finding every variant of SIP (or even products
targeted for the same environment) use OPTIONS to query for operational
status, but they all do it differently. What we're trying to do is wr
Hello all;
i would ask you about the draft of Using OPTIONS to Query for Operational
Status in SIP.
Can we use OPTIONS message with IMS to Query for Operational Status in
SIP?
Please Help me;
Thanks

It depends upon the transport and if you want to be compliant. Concerning UDP,
sending the 100 immediately is non compliant to RFC 4320 (which updated RFC
3261).
RFC 4320 section 4 "Normative Updates to RFC 3261":
"An SIP element MUST NOT respond to a non-INVITE request with a Status-Code of
Hi Bhupesh,
1. Size of packet is determined by its payload and header length. Length of
data is 16bit value in IP header, the data vary from 20 (size of header
portion) to 65535 bytes assuming.
2. Like I said it depends on data and the underlying transport mechanism
used to send SIP message. Refer
Hello,
I had some basic questions, i hope people don't mind answering.
1. What is the size of an IP Packet ?
2. Is one SIP message, example, an INVITE or an ACK, transmitted over one IP
packet or more than one IP packet ? Are IP packet sizes fixed or variable
(according to the SIP message size) ?
Hello all;
Thanks for replay;
Can we send 100 trying immediately for non-Invite transaction like REGISTER
request;
or we should follow the RFC 4320 for Make the best use of provisional
responses for NON-INVITE transaction; for example Allow 100 Trying after
Timer E reaches T2 (for UDP hops);
