[ABN] There is no need for any formal relation between signalling and
media. if you can share your use case you can get the useful replies.

Theoretically, it is acceptable to use different addressing schemes for
signalling and media. AFAIK, There is no constraint to use same IP version
for both media and signalling.

It is very well possible to publish the IPV6 media address (in SDP) whereas
IPv4 is being used for SIP signalling purposes.
