DTMF Issues

Recommended Posts

There is one problem I wonder if you can help me with. We try to recording all income/outgoing calls, we have problem with the file name and recording the dtfm input. According to Wiki (http://wiki.pbxnsip.com/index.php/Recording ), $i is used to indicate direction of the call (incoming i /outgoing o); and $u/$n are replaced with the calling/called party number. But it is not working in my case.

Looks like that for the incoming call, it’s always use our public phone number as calling party. For example, I called from my cell phone

(770-XXX-XXXX) to our public phone (678-373-4755), The file is “16783734755-16783734755-111547-i.wav” which is not correct. It should be “1770XXXXXXX-16783734755-111547-i.wav”. Also, when I called from an extension (5090) to my cell (770-XXX-XXXX), the file is “5090-917703135695-114558-i.wav” which is not correct. It should be

“5090-917703135695-114558-o.wav” . Here is my setting for the Record–

Location “$r/$d/$u-$n-$t-$i.wav” .

Out of band-DTMF is problematic as the PBX just passes it through without converting it into inband.

 

The direction problem is because the PBX has problems determining if this is a inbound-outbound (redirected) call or not.

 

We probably have to change the recording model so that we define the point where the recording takes place. For example, it would make sense to define that the recording always takes place on the trunk call leg. At the moment the model is not very clear and that leads to difficulties understanding why something is inbound or outbound.
