How to connect on-receiving-rtcp signal in rtpsession?

Hello,
While awaiting the response of Sebastian, please help me ;-)
because I could not /get the rtpsession object from the 
"internal-session" property on the rtpsession element/, I tried to 
intercept RTCP packets by setting a callback to sinks connected with 
RTCP streams, using:
> gst_pad_add_probe(srcpad, 
> GST_PAD_PROBE_TYPE_BUFFER,(GstPadProbeCallback) rtcp_probe_cb, NULL, 
> NULL);
Is it the same as intercepting "on-{sending|receiving}-rtcp" signals?

Thanks in advance,
Philippe
