Privacy headers support

Hello,

I have problem to properly configure sip privacy for Cisco 3945E running 15.2.(3)T IOS rel.
I have exact configuration as described in http://www.cisco.com/en/US/docs/ios-xml/ios/voice/cube_sip/configuration/15-0m/voi-paid-ppid-priv.html and other cisco web pages, but privacy headers generated by outgoing dialpeer are not compliant with RFC3325 or RPID draft.

voice service voip
address-hiding
allow-connections sip to sip
  cause-code legacy
sip
  header-passing
  error-passthru
  early-offer forced
  midcall-signaling passthru

and incoming and outgoing dialpeers like following:
dial-peer voice 30 voip
corlist incoming o-XX1
description INCOMING numbers
service authapp
session protocol sipv2
incoming called-number .+
  incoming uri via 100
voice-class codec 2
fax protocol pass-through g711alaw

dial-peer voice 130 voip
corlist outgoing t-XX1
description Outgoing numbers
huntstop
destination-pattern 481112233..
  session protocol sipv2
session target ipv4:10.10.10.12
incoming uri via 27
voice-class codec 2
fax protocol pass-through g711alaw

sip-ua
no redirection
retry invite 2
reason-header override

sip-ua has remote-party-id command provided so it is enabled by default.

So any privacy header associated with incoming INVITE message should be mapped to RPID,

Incoming INVITE looks like following:

INVITE sip:48111223344@10.10.10.19:5060;user=phone SIP/2.0
Allow: UPDATE,REFER,INFO
Call-ID: 30620-RW-0035511e-1cf464fb2@wog.pl
Contact: <sip:10.10.10.10:5060>
Content-Type: application/sdp
CSeq: 2481799 INVITE
From: "Anonymous" <sip:anonymous@anonymous.invalid>;tag=30620-ER-0035511f-27a46d3e2
Max-Forwards: 30
P-Asserted-Identity: <sip:222334455@wog.pl;user=phone>
Privacy: id
To: <sip:48111223344@10.10.10.19;user=phone>
User-Agent: MainSS
Via: SIP/2.0/UDP 10.10.10.10:5060;branch=z9hG4bK-5DA9-2D6AB2
Content-Length: 211

v=0
o=cp10 136735199451 136735199451 IN IP4 10.10.10.11
s=SIP Call
c=IN IP4 10.10.10.11
t=0 0
m=audio 31652 RTP/AVP 8 0
b=AS:80
a=rtpmap:8 PCMA/8000/1
a=rtpmap:0 PCMU/8000/1
a=ptime:20
a=sendrecv

but outgoing one has following pricacy contents:

Remote-Party-ID: "Anonymous"<sip:anonymous@10.10.10.19>;party=calling;screen=no;privacy=full
From: "anonymous" <sip:anonymous@10.10.10.19>;tag=1B76DBE0-2405
Contact: <sip:anonymous@10.10.10.19:5060>

which is wrong.

Changing remote-party-id to pai (voice-class sip asserted-id pai) does not change anything (pai to pai) resulting:

From: <sip:anonymous@anonymous.invalid>;tag=1B809042-930
P-Asserted-Identity: "Anonymous" <sip:anonymous@10.10.10.19>
Privacy: id

The problem is that RPID or PAI or even PPI is not compliant with RFC3325/draft.Have you guys any hints of how to solve this or point me where i made mistake in my configuration.

Thanks in advance,
Mac.
