According to the RFC, this is a just an identifier (not an ordering), the
foundation:

https://tools.ietf.org/id/draft-ietf-mmusic-ice-sip-sdp-14.html#rfc.section.5.1
https://tools.ietf.org/html/draft-ietf-ice-rfc5245bis-00#page-23

So, if I understand correctly, I can just filter the address and keep sending
the same thing.

Can you confirm? If so, we can just close this bug.
