Media Gateway Control Protocol (MGCP) Voiceband Data (VBD) Package and General-Purpose Media Descriptor Parameter Package
RFC 6498

[Ballot comment]
I support Sean's discuss. 

I would like to clarify if (1) there is a mandatory to implement security mechanism, or (2) if it is mandatory to implement one of the two security mechanisms.  Either (1) or (2) is okay, but I think it would be bad if the answer to both is "NO".

Additional detail is definitely needed to have interoperable implementations using IPsec.

I think additional information on SRTP is also required, but I could be wrong. :)

[Ballot discuss]
#1) The security considerations recommend both IPsec and SRTP, but one is not specified as the mandatory-to-implement.  In order to achieve interop one needs to be picked or are you suggesting both be used?

#2) The security considerations say use IPsec as the end-to-end protection scheme.  It needs to say a whole lot more.  See Section 8 of RFC 5406.

#3) In the same veil is just pointing at SRTP sufficient to get two interoperable solutions?

We need a revised I-D to address the IETF LC comments. In particular, the security review by Carl Wallace and the Gen ART review by Wassim Haddad.

IANA questions/comments:

- Do you want/need a registry of Symbols defined in Section 3.1?

- Do you want/need a registry of CoordinationTechniques as defined
in Section 3.1.1?

- Do you want/need a registry of ReasonCodes as defined in Section 3.1.1?

- In Section 4.1 you define a LocalConnectionOption but don't register
it in the LocalConnectionOptions Sub-Registry. Should you register
this option?

Upon approval of this document, IANA will make the following assignments
