I am wondering if
freeswitch isn't detecting my client<br>sending audio and interprets it as silence and therefore hangs up. The<br>voicemail message itsel does contain everything said right up to the hang<br>up.<br><br>Sometimes I can call between extensions if they are on the same side of<br>the VPN subnet (say 101 calling 101 and they both are coming from<br>192.168.1.0/24 via 10.8.0.0/24)<br>If 100 is on 10.8.0/24 and 101 is on 10.9.0.0/24 freeswitch just says user<br>is unavailable.<br><br>I'm suspecting this is a NAT issue, all the reading I have done talks<br>about "external sip and rtp ip" in my case my trunk hooks up from private<br>ip to private ip, it's the kamailio that's supposed to do the NAT (which I<br>have verified works fine, I can place outgoing calls through it from other<br>PBXs no problem with two way audio and working as it should be).<br><br>I'm not sure if there is a way to enable nat or not with freeswitch. One<br>thing I have done (as I've
found this worked for some people) is set all<br>references to sip-ip ext-sip-ip, rtp-ip and ext-rtp-ip to 10.0.0.34 (my<br>freeswitch eth0). There are no other adapters on the box.<br><br>I am hoping that as this is my first time setting up freeswitch that one<br>of you freeswitch experts can point me in the right direction :)<br><br>Thanks in advance guys!<br><br><br><br>_________________________________________________________________________<br>Professional FreeSWITCH Consulting Services:<br><a ymailto="mailto:consulting@freeswitch.org" href="mailto:consulting@freeswitch.org">consulting@freeswitch.org</a><br><a href="http://www.freeswitchsolutions.com/" target="_blank">http://www.freeswitchsolutions.com</a><br><br>FreeSWITCH-powered IP PBX: The CudaTel Communication Server<br><a href="http://www.cudatel.com/" target="_blank">http://www.cudatel.com</a><br><br>Official FreeSWITCH Sites<br><a href="http://www.freeswitch.org/"
