rickyjperez Posted March 26, 2009 Report Share Posted March 26, 2009 If you are using callback, and when call comes back to the cellphone or landline, after that it asked to dial the destination number, can it be setup to call an extension number on the pbx. Also I am setting up so it does not use the auto attendent, but when it goes directly to the callback or i use the hunt group i do not get dtmf tones, but when i use the auto attendent is works great Quote Link to comment Share on other sites More sharing options...

You cannot do something else than dialling the person that became available. Did you try to press "*"? I am not sure, but it could be that this is a escape code that brings you back to the auto attendant. Quote Link to comment Share on other sites More sharing options...

If i dial the auto attendent and dial the ext for the callback the dtmf works, but if i point a number via hunt group to the callback extension it does not work here are the logs. The inbound access number i am dialing is 973 528 7903 logs are attached Quote Link to comment Share on other sites More sharing options...

(It is hard to imagine how you would find out if a hunt group becomes available again.) Quote Link to comment Share on other sites More sharing options...

Even when I place the access number added to the callback extension, no dtmf tones Quote Link to comment Share on other sites More sharing options...
Vodia PBX Posted March 30, 2009 Report Share Posted March 30, 2009 Even when I place the access number added to the callback extension, no dtmf tones If the other side uses only G.729 without and out of band DTMF (RFC2833/4733), DTMF is not possible as G.729 distorts the tones, so that the detection becomes impossible.
