style='font-size:10.0pt;font-family:Arial'>I’m a Cisco 7940 phone using
SCCP. My setup is a private network with the * box acting as dhcp server
and also tftp server. The phone loads and dials out fine. I can
hear the other person, but there is no outgoing audio. I’ve read
that this is an RTP problem and have tried making some changes in /etc/hosts to
point to my * box IP but with no luck. When I do a tcpdump I see that the
RTP packets are sent to 0.0.0.0. How do I get the phone to send to the *
box?<o:p></o:p></span></font></p>
