Hello Jenkins Builder,

I'd like you to reexamine a change.  Please visit


to look at the new patch set (#2).

mgcp_test: do not send rtp packets

The sendto() override in mgcp_test sends rtp packets out. This
might be a problem for some test hosts. e.g. on OBS, sending packets
fails with an error message, which exits sendto() early and hence fails
to send the expected amount of "Dummy Packets". Interestingly enough
calling the real sendto is not necessary to run the test at all.

Remove the execution of the real_sendto and just return len.
