Asterisk does not forward RTCP packets

Dear all,

I am using the Asterisk version 1.4.11.

I have an issue with my VoIP phones.
These phone must exchanges RTCP packets in order to check and control the RTP flow. Using canreinvite = no, Asterisk remains in the middle of the RTP flow.
Asterisk get the RTCP packets incoming from the phones and do not forward to the remote phone; it considers them for itself.

On the opposite side I see many packets from Asterisk to both the phones, but normally all these packets contains : number of error packets =0 .
How is possible to forward the RTCP packets?

Just like the RTP packets…

Thank you for your attention.

We are also experiencing this issue, if someone could help it would be appreciated
