Description

In Abis/IP we are using fully-symmetric RTP over a UDP flow between a given set of IP:Port tuples on either side of the Abis link. As such, we would normally expect that the sockets are not just bound to a local port on the BTS side, but that they're also connect()ed to the remote side.

We are using osmo_rtp_socket_connect() in source:src/common.rtp.c and asume that this actually happens, but a look in netstat indicates differently :(
