Dear,
with asterisk 1.6.2.18 and sccp-bv3stable on two servers, we tried to
register about 1200 cisco phones, for a company.
in out of official hours, all 1200 phones registered and the cpu and ram
was below 5%.


In my experience, registering a Cisco phone was never an issue with sccp 
but it is hardly a test to see if it works.



H323 is the protocol for incoming calls, and SIP for outgoing ones.


I'm not sure what the state of chan_h323 is in Asterisk so you should 
ask around if there is anyone who uses chan_h323 in production and how 
reliable it is. Or hire a consultant to fix your problems. As far as I 
know the original developer of chan_h323 has not touched the code in a 
long time and no longer maintains it.



in official hours, with only 10 calls, the cpu went more than 100% , and
crashed.
the bt full result of gdb was attached


I am not a developer so can't tell you what is going wrong. According to 
the chan_h323 README you need PWLib 1.10.0 and you are using 1.10.3.



I have some questions now,
1-is any problem in the attached report.
2-does asterisk 1.4 more stable than 1.6 in this case?


Can't you test Asterisk 1.4 and see if that works? Also did you try the 
other h.323 channel driver (chan_ooh323) which is part of asterisk 
add-ons? For Asterisk 1.6 you can find it here:

http://downloads.asterisk.org/pub/telephony/asterisk/releases/asterisk-addons-1.6.2.3.tar.gz

Should Asterisk not be the proper solution for your customer's situation 
then maybe get a dedicated h.323 -- sip gateway or have a look at 
FreeSWITCH or Yate.


Even if the h.323 part works flawlessly then make sure you test the sccp 
part very thoroughly. I have only experience with sccp v2 but have never 
seen that work reliably.

Patrick
