Did some more troubleshooting. Here are some interesting notes:

>> Note #1: Tried to simplify the scenario and removed the conversion from fd -> gsocket (i.e. avoid g_socket_new_from_fd). Instead, I use gsockets all the way:

----
GSocket *gsocket = NULL;
GSocketAddress *rtp_sockaddr = NULL;
GInetAddress *inetaddr = NULL;

gsocket = g_socket_new (G_SOCKET_FAMILY_IPV4, G_SOCKET_TYPE_DATAGRAM,
G_SOCKET_PROTOCOL_UDP, NULL);
inetaddr = g_inet_address_new_any (G_SOCKET_FAMILY_IPV4);
rtp_sockaddr = g_inet_socket_address_new (inetaddr, 16384);
g_socket_bind (gsocket, rtp_sockaddr, FALSE, NULL);

g_object_set (G_OBJECT (self->sm_udpsink), "socket", gsocket, NULL);
----

Again, I get the exact same problem; this means that the problem is not with
the conversion. 

>> Note #2: Instead of setting the socket property of the udpsink of my pipeline, I did that for the udpsrc (the rest of the code remains the same):

----
...
g_object_set (G_OBJECT (self->sm_udpsrc), "socket", gsocket, NULL);
----

In this scenario, I got no issues! Which is pretty strange. I mean this means
that the address family issue occurs for the udpsink but not for the udpsrc.

>> Note #3: I even tried using specifically the IP the iPhone gets from my router using rtp_sockaddr = g_inet_socket_address_new_from_string("10.0.0.10", 16384), but again the same problems.

Any ideas are most welcome

Thanks a lot in advance,
Antonis

P.S. Here's my pipeline in case you are interested:

autoaudiosrc ! capsfilter caps=audio/x-raw,rate=44100 ! audioconvert !
audioresample ! queue ! mulawenc ! rtppcmupay ! udpsink name=udp-sink udpsrc
name=udp-src
caps=\"application/x-rtp,media=audio,clock-rate=8000,encoding-name=PCMU\" !
rtppcmudepay ! mulawdec ! audioconvert ! audioresample ! autoaudiosink
