40x8 EE, secure sip | sips | sip-tls

[thajacabela]

I would like test 40x8EE (4018, 4028, 4038) with secure sip.

*** Those devices support secure sip ?
The english data-sheet http://enterprise.alcatel-lucent.com/as ... asheet.pdf says:

Security:
Certificates for 802.1x EAP-TLS, HTTPS downloading

BUT this one in german http://cdn.billiger.com/dynimg/Q-NeqXCc ... e005e7.pdf says:

Sicherheit
•SIP-over-TLS für Protokollverschlüsselung, SRTP/SRTCP für
Sprachverschlüsselung
•Zertifikate für 802.1x EAP-TLS, HTTPS-Download und SIP TLS (Alcatel-Lucent- oderKundenzertifikate)

-google translate-
safety
• SIP-over-TLS for protocol encryption, SRTP / SRTCP for voice encryption
• Certificates for 802.1x EAP-TLS, HTTPS download and SIP TLS (Alcatel-Lucent or Credentials)

*** If the devices support secure sip, what about the params in configuration? (sipconfig.txt, sipconfig-MAC.txt)

*** Any technical documents about those terminals and SIP(S) deeper than http://enterprise.alcatel-lucent.com/as ... e-ed02.pdf ?

Thanks in advance and sorry my english.

PD: I really don't know what's the difference among secure sip, sips and/or sip-tls...
