yes, I'm afraid the media subsystem does not quite support IPv6.
But shouldn't be a big task either. Basicly, you'd need to patch:
Basicly you'd need to patch:
- sofsip-cli/src/ssc_media_fsgst.c:farsight_netsocket_bind_udp_port()
- either
- src/ssc_media_fsgst.c:priv_setup_rtpbin()
- src/ssc_media_gst.c:priv_setup_rtpelements()
- and pass the media address parameter from signaling (ssc_sip.c)
to the media object (the params are passed in
ssc_sip.c:priv_create_ssc_media())
Patches to fix these are very much welcome!
The signaling side should be ok with IPv6. We've also tested the stack
with a proprietary media stack that support IPv6, but never did test with
sofsip-cli.

This should be fixed now in the devel tree. Thanks for the report!

Yep, this is because of the abovementioned shortcomings. The 'media-addr'
is not currently passed to the media stack, and is only used in SDP
offer/answer. :(
