Thanks Samuel. I have an idea after reading your comment. Do you
mean the system busy situation is not relationship with error 407, 408
and 481?
For the sipp tool, I have figured out how to use it. However, for the
high load performance evaluation. I don't have idea how to do it and
I can't find any information about it as well. Could you give me a
reference (link) about it?
Say, I have a 50 user accounts in the csv file and it will be loaded
for a build-in scenario with RTP package (uac_pcap.xml). Do I need to
find 50 receving parties for that 50 callers? How can I test it in
the receiving end without having 50 real receving parties?
You are right to figure out whether it is a config file or the network
problem. The config file that I use is listed below. From my limited
knowlegde, I can't find any clue to figure out whether it is a problem
of the configuration file. Could you please take a quick look of the
config file and give me some hint to improve it?
Thanks a lot!

This probably happens because all the listeners are busy (DNS lookup,
mysql queries, exec_*) and the incoming requests are not answered.
That's why your UA shows the can't logon because they get no answer.
This requests are "queued" and they are processed when the load
decreases, and that's why the system "reverts to normality".

This is returned everytime the route reaches a proxy_challenge
statement. It's used to obtain the user credentials in the digest
algorithm. Usually the first time a UA registers is challenged and the
challenge parameters are valid for a period of time. After this
period, the digest challenge has expired and a new challenge will be
issued.
> 408 - request timeout
This usually happens when openSER has relayed a request and does not
receive any response within fr_inv_timeout (this name may have changed
since the time I checked and now).
> 481 - call leg transaction does not exit
This error is returned by UAs when they receive a request within a
transaction which does not exists| has ended.
As an example:
when the ACK (after the INV-OK) is lost, the UA terminates the invite
transaction. When the other UA sends a BYE, since there is no
transaction, this BYE is answered with a "481 call leg transaction
does not exist".

Take a look at sipp for high load performance evaluation.
I guess there's some bottleneck either in your config file or in your
network that leads to this "network congestion" .
Hope it helps,
