No problem. As I understand it this is probably caused by your ADSL router supporting symmetric NAT. The SIP signalling ports I believe are well known, but the RTP ports are randomly assigned. I think symmetric NAT expects incoming connections to be made on the same outgoing port numbers - so if the incoming RTP streams are on different ports this breaks.

The "Workarounds" section here has some useful information:

And also:

Cheers,

Dear Dave,
If I open up ports 5000 to 35000,
I can here the female voice in Echo Test and, but after a "crying queek" is playing until I stop the called.
I can here the female voice in Conference Room, after there is only silence.

Do you have any ideas, do you need my output.txt again?
I did it anyway and I have found this:
packetsSent       = 2333
    octetsSent        = 373280
    averageSendTime   = 20
    maximumSendTime   = 20
    minimumSendTime   = 20
    packetsReceived   = 2330
do you want me to send you the whole file?

Dear Yannick,
when I start EKIGA and try the Echo test or the Conference Room I cannot here anything at all, however I can see that the capture tab is moving when I am speaking at the mic.
 

I have:
on my ADSL router
- enable in NAT port forwarding (ports 5000-5100)
 

If you open up ports 5000 to 35000, does that change anything?

Cheers,
