How are you building your pipeline for the receiver, and if GStreamer is
used on the sender... how does your pipeline look there?

You should get a GST_MESSAGE_ELEMENT on the bus of the receiver
pipeline, with a "dtmf-event" message. This is emitted by the DTMF
depayloader. Is that payloader in the pipeline?
