<div><font face="Arial" size="2">there is no audio. </font></div>
<div><font face="Arial" size="2">I have made port fordwarding in the router 1. I
have opened ports 5060-5070 to SIP and 10000-20000 to RTP.</font></div>
<div><font face="Arial" size="2">In the sip.conf file I have externip, localnet,
bindport, bindaddres, nat = yes etc.</font></div>
<div><font face="Arial" size="2">I have used wireshark to see the frames and there
is rtp traffic in both direccion so i donīt know what the problem
is.</font></div>
<div><font face="Arial" size="2">I have used the x-lite in the same LAN than the
ip-phone and all is good so the two phones works fine.</font></div>
<div><font face="Arial" size="2">What is the problem? Thank you in
advance</font></div></blockquote><div><br>a pointer to check, in rtp.conf just make sure that rtp start port is set explicitly rtpstart=10000, cause default rtpstart is 5000 so opening port 10000-20000 in router without setting this may not help.<br>
