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

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.

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.

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.
