Joshua Colp has uploaded a new change for review. ( https://gerrit.asterisk.org/5135 )
Change subject: res_pjsip_transport_websocket: Add support for IPv6.

res_pjsip_transport_websocket: Add support for IPv6.
This change adds a PJSIP patch (which has been contributed upstream)
to allow the registration of IPv6 transport types.
Using this the res_pjsip_transport_websocket module now registers
an IPv6 Websocket transport and uses it for the corresponding
traffic.

+Subject: [PATCH] Add support for registering IPv6 transport type.
+
+This change allows an IPv6 transport type to be registered
+and used. This does require that the IPv4 transport immediately
+preceed the IPv6 transport, but
+
+The IPv4 transport is found (if available) and the
+IPv4 flag added to its type to match how the finding of
+IPv6 transport types works.
