Section 5 has (and IIRC other places are similar): SIP User Agents (UAs) that support and intend to use trickle ICE are required by [I-D.ietf-ice-trickle] to indicate that in their Offers and Answers using the attribute "a=ice-options:trickle" and MUST include the SIP option-tag "trickle-ice" in a SIP Supported: header field. It's a little strange to me to say that the core trickle spec mandates specifically the "a=ice-options:trickle" attribute, which is only defined in this document. The core spec does mandate some form of indication, but maybe it is more clear to phrase as something like: SIP User Agents (UAs) that support and intend to use trickle ICE are required by [I-D.ietf-ice-trickle] to indicate that support in their Offers and Answers. For SIP, this is done using the attribute "a=ice-options:trickle", and the SIP option-tag "trickle-ice" MUST be included in a SIP Supported: header field. In the scenario depicted in Figure 10, how is it indicated to Bob that Alice supports trickle (and should that mechanism be indicated in the figure)?

I share Adam's concern over the use of IPv6 addresses in the srflx example.
