I have vitually the same problem as posted below.
https://supportforums.cisco.com/message/3797939#3797939
After talking to TAC, the 3rd Party PBX is sending the SIP Contact Header and forcing Call Manager 8.6 to reject the call with a "SIP/2.0 400 Bad Request - 'Malformed/Missing Contact field'"
In my case calls all inbound calls are failing when marked as anonymous/private
PSTN <PRI> Nortel CS1k <SIP> Avaya Session Manager <SIP> Call Manager 8.6
I do not have CUBE, simply SIP Trunk directly from AvayaSM to UCM.
So I was wondering if anyone has any Normalization script advice. I've been referring to the URL below but not much luck.

Current Incoming Private SIP Contact Header:
e.g.
Contact: <sip:anonymous.invalid;phone-context=+1@company.com:5060;maddr=1.1.1.1;transport=udp;user=phone>
Wanting to replace “anonymous.invalid;phone-context=+1” with “00000”:
e.g.
Contact: <sip:00000@company.com:5060;maddr=1.1.1.1;transport=udp;user=phone>
...or any other advice welcome.
Thanks in advance!
