             Summary: [patch] STUN crashes when SIP is bound to ipv4 and ipv6
                 Key: ASTERISK-21936
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-21936
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Resources/res_rtp_asterisk
    Affects Versions: 11.4.0
            Reporter: Torrey Searle


When chan_sip has ICE support enabled and is bound to both ipv4 and ipv6 using the [::] any bind address.  res_rtp will only add ipv6 candidates.  The result of this that asterisk is unable to build a checklist in the case of an ipv4 ICE call and crashes on an assertion failure

My proposed fix is to instruct pjsip to build a list of ipv4 and ipv6 addresses in the case the ipv6 "any interface" has been used
