--- Comment #2 from Mikel <mgallar1967 at gmail.com> ---
We have resolved this problem yesterday. 
The problem was not in gstreamer development. Instead, it was in sdp previous
negotiation.
The RTP/RTCP stream occurs after a session negotiation, with sdp parameters
exchanged in SIP INVITE and UPDATE commands.
When "RS" and "RR" parameters were set to "0", RTCP packets worked OK (sent and
received) for most telco operators. But in another Telco operators RTCP packets
were sent (but not received). If RTCP packets were not received, the signals
"on-ssrc-active"/"on-bye-ssrc" were not executed.
After setting these sdp parameters to correct values, it has worked correctly.
Thanks.
