What is the proper way to signal RTP support for both IPV6/IPV4 in the SDP?
Should there be a single m=line with two c=lines:
m=audio 25000 RTP/AVP 0
c=IN IP6 2001:DB8::1
c=IN IP4 192.0.2.1
or two m=lines with two 2 c=lines:
m=audio 25000 RTP/AVP 0
c=IN IP6 2001:DB8::1
m=audio 25000 RTP/AVP 0
c=IN IP4 192.0.2.1
Thanks in advance.
