-----------------------------------------

             Summary: ICE fails with no candidate nominated
                 Key: ASTERISK-27646
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-27646
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_sip/General
    Affects Versions: 13.18.0
            Reporter: Thomas Guebels


Since the change made in ASTERISK-27088, we have intermittent ICE issues.

The ICE negotiation fails on the asterisk side with all checks succeeded but none nominated.

On the browser (Chrome 64) side, it thinks that ICE succeeded but there is one-way voice and the call soon stops because asterisk doesn't reply to STUN pings anymore.

It seems to be timing dependent as it can only be reproduced with at least 2 network paths with similar latency. When one is noticeably slower, it doesn't happen.
