> 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
