DTMF detection doesn't work after a dialplan transfer
by Iskren Hadzhinedev 21 Nov '14

21 Nov '14

Hi everyone, using version 1.5.15b+git~20141109T085007Z~eb30491688~64bit (git eb30491 2014-11-09 08:50:07Z 64bit). When I use "transfer" in the dialplan to send someone to another context, DTMFs aren't detected. They pop up in the debug console, but voicemail seems to ignore them. Is there a way to workaround this? Thanks! Kind regards, -- Iskren Hadzhinedev

Save voicemail in opus format
by Kamil Nigmatullin 21 Nov '14

21 Nov '14

Hello. I want to save voicemail in opus codec so that client could listen it without transcoding. I set extension to opus instead of wav. Freeswitch started to write file with opus extension and it content of the file looks diffrent than wav. But I can playback this file even with unloaded mod_opus. VLC cannot play this file. How can this be explained? -- Kamil Nigmatullin Skype: kamil.nigmatullin

Presence question
by Kamil Nigmatullin 21 Nov '14

21 Nov '14

One of our clients wants to switch on presence feature, but they have 140 lines of FXS that does not support Publish/Subscribe function. Is there a way to achive this using data in freeswitch (if Registered or Busy)? I know that it is a silly question but they asked me to ask anyway, so will anybody just confirm that it is not possible? -- Kamil Nigmatullin Skype: kamil.nigmatullin

Conference recording
by Oleg Stolyar 21 Nov '14

21 Nov '14

Hi, I am planing to record conference using the auto-record param. My question is this: If the machine runs out of disk space, will FS just stop recording or will bad things like crash happen? Same question for logging. Thank you

mod_conference stereo? record stereo wav?
by Stephen Dame 20 Nov '14

20 Nov '14

Question, we are successfully connecting chrome/firefox with opus48, 2 channel stereo to mod_conference user master build. Recording the conference seems to only record 1 channel Couple questions, did not see any documentation on stereo in wiki. 1) Do we need to add a param to conference.conf.xml profile to have the conference mix stereo? 2) What is the proper way to record the conference in stereo wav file? Thanks in advance. Regards, Stephen

Opus Codec Error
by David Shemesh 20 Nov '14

20 Nov '14

Hope someone can help with this: I am experiencing a strange issue using Opus. The call is from a registered client to a landline through a sip Trunk. Freeswitch is transcoding From Opus to PCMU and after about ~1min the call drops with "switch_core_io.c:1282 Codec OPUS (STANDARD) decoder error!" and the call gets disconnected. It looks like this happens only when i enabling the jitterbuffer. I was able to reproduce this using various Clients (Csipsimple, Jitsi) & Sip trunks. it seems like its has something to do with freeswitch's implementation of OPUS.

problem with eavesdrop() sending null RTP for 15-30 seconds
by Nathan Neulinger 20 Nov '14

20 Nov '14

Seeing an interesting issue with sending an eavesdrop where the outbound call gets established, but no useful audio is transmitted until around 15-30 seconds into the call. Prior to that point, FS is transmitting all identical RTP frames with the payload containing: 24 1c 61 7a 7f 55 55 55 50 06 83 ff ff ff ff ff ff ff ff ff ff ff ff aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa af ff ..... ff This is minimal version of command that was being issued: originate sofia/internal/6679(a)voice-dev.mst.edu &eavesdrop(ca887b3b-013f-4972-aa7c-37a7b132bf52) Reproduced with head of master as of a few minutes ago. Restarting FS and trying again, the FIRST attempted eavesdrop seems to not have the long delay, but the second one does. The 'dummy' payload appears to have the same content in subsequent requests. Interestingly, if I let the outbound call ring longer before I pick up, the delay appears to be reduced by the period of time I let the phone ring for. if I pick up immediately, 25-30 second audio delay approx, if I pick up after 25 seconds of ringing, I get only a couple second delay. Any idea where to start looking for where this buffering might be getting introduced? For the "only eavesdrop" case it's not as big of an issue, but when you switch over to barge, can't really have multi-second audio delay. -- Nathan ------------------------------------------------------------ Nathan Neulinger nneul(a)mst.edu Missouri S&T Information Technology (573) 612-1412 System Administrator - Architect
