Hi List, We are using a carrier who insists on sending DTMF INBAND. I was using the start_dtmf application in my dialplan but this was generating a lot of talk off. I've switched to spandsp_start_dtmf application and this seems to work without any issue.! My next issue is that we have a customer who is using asterisk and an IVR that ends up in the voicemail application. Freeswitch seems to be stripping the 'BEEP' out of the RTP that the voicemail application sends. It does it a bit randomly - and I initally thought it was the spandsp start dtmf application. I've been playing with the thresholds and twists etc but it doesn't improve. I've captured the RTP and the leg from the asterisk PBX has the voicemail 'BEEP' but the leg to the carrier doesn't. I've done /event plain all when the server isn't busy to see if I can spot something happening when the BEEP is in the RTP but nothing comes up. It doesn't seem to be the span dsp dtmf stuff causing this. I'm at a bit of a loss. Anyone any ideas? Thanks, Brian
Did you figure this out? If not -- save a PCAP of each leg + the FS log for us to look at. Also.. since you've been looking at this: can I somehow use spandsp_start_dtmf to just strip the DTMF from inband? I've got an uncooperative carrier who's been sending rfc2833 and usually inband also and that messes up when I bridge to a remote system... I already have the dtmf in rfc2833, I don't want it duplicated, just removed. -Avi
Did anyone get anywhere with this ?? I also have an edge case where I need FS to remove inband DTMF. Does anyone have any suggestions ? Jay On 1 December 2013 23:28, Avi Marcus <avi@avimarcus.net> wrote:
