> "INFO - RFC2833 transcoding". A sends DTMFs using INFO, B Party supports RTPEvent for DTMFs, so asterisk has
> to regenerate the digits for B side using RTPEvent, The main point of interest in this case that
> A party sends INFO packets after B has finished playing the audio pcap meaning that A party sends INFO packets
> when there is silence on the channel between asterisk and B side.
> Expected Outcome: All digits should be regenerated properly as RTPEvent packets on B side.
> Actual Outcome: No DTMF End packet is received for last digit
