This should be no problem. Use ngrep or tcpdump to sniff all the SIP
traffic. If a phone loose registration, write down the phone and the time.
Then take a look at the network dump and find the REGISTER transaction
which failed and analyze. This will give you more insight.

I have set an openser in a cs department with almost 50 sip phones
connected to it. It is a very heavy loading environment. Every sip
phone may make/receive almost 20-40 calls per minute. In such
situation, most of the sip phones will experience a logon problem.
They will failed to logon (in the display of the sip phones show wait
logon) and 1 minute after, they can logon to the system. This
situation will repeat for every sip phone in the system.
I wonder what is capacity of the openser. As I expect, it should
handle over 1000 sip devices connected concurrently (correct me if I
am wrong). I also wonder any misconfigure in the configuration file.
I set children to 4 in the file. Do I need to increase the children
value? Is it useful for solve this situation? If not, what is the
possible action to solve the above problem?
