IP Office/handsets "H.323 protocol" is Proprietary?

Hi,
i am developong VoIP recorder that works for SIP,H323,Skinny. I am
adding Avaya IP Office support now, and it correctly records the RTP
streams, but cannot recognize the signalization.
We are using standart Avaya IP Phones for internal extensions and i am
recording voip sessions between these phones and the switch.
Avaya states it uses H.323 protocol for their VoIP signalization, but
after analyzing their protocol with Wireshark it appears its not a H.
323 protocol at all, but some empty H.323 informational messages with
Non-standard elements.
There is no Callsetup,Alerting,Connect messages.
So i guess there is Avaya Proprietary protocol encapsulated in thos
Non-standard elements. Also the protocol seems encrypted. Is there any
way to turn of this encryption off as the Avaya switch usually resides
in a private network and such security is not needed.
Anyone know if i am right? Is there any info on this Avaya protocol?
Thanks!

I would check that again, if it was not standards based then how is it we are able to link the the IP Office to other brand PABX's using H.323?

When I look at call logs from the system it uses stock standard H.323 information messages.
