[SIPForum-discussion] ICE - Connectivity check Algorithm

[rahul sankanur]

Hi Manoj,
Thanks for the reply.
My question was whether connectivity checks for the media streams will
begin simultaneously or one after the other.
For Eg:
If I have 2 streams say Audio and Video and Audio has highest priority. The
connectivity checks for video will start after completion of Audio or it
will start when Audio checks are still going on.
