In case of negotiating with server (may be a gateway), IMHO, the server would like not to do connectivity check, it is simpler and faster to work in ice-lite and passive mode.

Thanks,

+rtcweb

WebRTC endpoints must implement full ICE. Legacy (non-WebRTC) endpoints can use ICE Lite, but as mentioned in RFC5245, S 2.7, full ICE is preferred.

Dear Person,
 
I have seen the below in the draft of:   http://tools.ietf.org/html/draft-ietf-rtcweb-jsep-05
 
Attributes other than the ones specified above MAY be included,
except for the following attributes which are specifically
incompatible with the requirements of [I-D.ietf-rtcweb-rtp-usage],
and MUST NOT be included:
 
o  "a=crypto"
o  "a=key-mgmt"
o  "a=ice-lite"
 
 
But in draft of :  http://tools.ietf.org/html/draft-ietf-rtcweb-rtp-usage-11  
There is no phrase that prevents a WebRTC user to be ice-lite
 
 
Can you pls clarify:
-          Where is it mentioned that ice-lite cannot be one of the participants of WebRTC
-          What is the reason that no side can be ice-lite  (as if one side is full-ice, there is still STUN and connectivity checks etc.
 
Thanks
RD
 
p.s. - what is the correct email address for this type of questions ?  (Thanks and sorry)
