Most passive taps require you to provide two interfaces to capture both directions. Some of them can also aggregate. Can you check yours ? Another option is port mirroring.

I added a facility to playback IAX2 calls even when only 1 direction of traffic is available. You will of course only hear one party speaking. I have sent you an email containing a download link.


To Enable this :

1) Plugins -> Customize
2) Scroll down to the IAX2 section
3) Check the "Extract Unidirectional" option

Thanks,

WOW!!!! This works great! I will recommend this product to everyone. I haven't found any other product that will play back IAX2 calls. You fixed your code based on my problem. WOW!!! Outstanding service, prompt forum help, and good support for the free version I am using. Many thanks!
