Nobody knows something about this RTCP SR transmission ??<BR>
<BR>
If it is a configuration setting in Asterisk, my firewall or my SIP-phone ??<BR>
<BR>
<BR>
Kind regards,<BR>

This is a log entry on a public Asterisk-server. My SIP-client (Grandstream GXP2010) can perfectly register to this public Asterisk-server.<BR>
<BR>
My SIP-client is behind a firewall.<BR>
<BR>
Port 5060 is no problem because SIP-registration succeeds.<BR>
RTP is also no problem because the 2 endpoints can talk to each other.<BR>
RTCP seems a problem. So there is RTP-traffic on port 5036 (even port) and RTCP on the next port (5037).<BR>
<BR>
What does Asterisk mean when RTCP SR transmission is not permitted ????<BR>
<BR>
Is this a setting in Asterisk ? My Endian firewall ? My Grandstream SIP phone ??<BR>
<BR>
Thanks,<BR>

Jonas.
