Asterisk Listen on IPv6 and IPv4

We want asterisk server to listen on both IPv6 and IPv4 . so we have set bindaddr=::
One client is registered using IPv6 and second one using IPv4. Both clients are registered through proxy server.
Here ,We use asterisk as media server. It accepts the rtp from IPv6 client only and not from IPv4.

So, What is the way to listen and accept from both IPv6 and IPv4?

Using ā€œ::ā€ with chan_sip should do as you say, but Iā€™m not sure many people run it with both IPv6 and IPv4. What exactly happens for the IPv4 client (logs and SIP traffic)?

Thanks for reply.
we solved the issue.
