New features needed when playing files - playback application
by Clive Lansink 21 Mar '13

21 Mar '13

There are two features I need in the playback application for playing sound files for an IVR application I am developing. Maybe one feature is there but I don't think the other is but perhaps people could advise me about that. 1. I need to be able to start at a specified time offset in the file. When playing is interrupted, there is a variable that can tell the number of milliseconds of audio that was played. If I want to resume playing, I need to be able to start from that point, or in fact any arbitrary point, in the file. I think I can achieve this with the uuid_fileman API command so maybe that will work. When I last looked at this I was confused as to whether the seek parameter was samples or milliseconds. 2. I want to be able to vary the speed of playback but in such a way as to keep the overall pitch of the recorded voice unchanged. There are algorithms that do this and I presume they work by removing samples from or adding samples into the audio stream. I think uuid_fileman also has a speed subcommand which kind of worked when I played with it, but it was not constant pitch. The application I am working on is a replacement of a system that delivers human narrated information to blind people over the phone. The existing system uses old analogue Dialogic cards and has these features, and the replacement system should also have these capabilities. Recorded bulletins of information can be quite lengthy, maybe an hour or more to read right through. So this is perhaps not typical of IVR systems. People need to be able to skip around and possibly speed up or slow down the reading, but without altering the pitch of the narrator's voice. I know I can create the necessary functionality if I have the above features in the playback application. Note that the application will also use TTS to turn textual information into speech but that is a separate issue and not relevant here. The application still needs to handle human narrated information. Can anyone comment on these features and, if something needs to be added, how easy it would be to do this and how it might be done?

External voicemail issue
by Elliot Farmer 21 Mar '13

21 Mar '13

Hi all, I'm having an issue with the voicemail system when accessing via a Skype connect trunk. Internally all is working, however if I call my external Skype number from a PSTN line when the call is routed to voicemail I get a lot of intermittent speech loss during the IVR announcement and then after the beep I can hear odd sounds that I can only describe as digital interference type sounds. Also the IVR is very quick to say "the recording is below the minimum length" although if I speak quickly I can record a voicemail and it sounds fine during playback, not amazing audio quality but no major issues. The issue seems to be the same as http://lists.freeswitch.org/pipermail/freeswitch-users/2010-December/066258…, I have tried recording a greeting but the same issues occur. I'm running Freeswitch on CentOS 6.3 on a physical machine. Here are some logs http://pastebin.com/jmuks47q , I've tried to remove the phone numbers and IP addresses as I don't have permission from the owners to publish them on the internet. Thanks in advance for your help!

Poor audio quality due to rtp timing issues
by Garey Arrington 21 Mar '13

21 Mar '13

When making inbound and outbound calls I am getting slightly less than acceptable audio quality after a few seconds. The machine is a 64 bit Centos 5.5 vm running on Xen with kernel version: 2.6.18-194.el5 I am getting warnings like with each call: 2013-03-21 04:22:54.655968 [WARNING] mod_sofia.c:1274 Asynchronous PTIME not supported, changing our end from 30 to 20 and 2013-03-21 04:22:54.056083 [WARNING] switch_time.c:578 Increasing global timer resolution to 10ms to handle interval 30 I have tried the fix that I have consistently found for this issue which is to add this to external.xml: <param name="rtp-autofix-timing" value="false"/> But this makes the audio quality so bad you can hardly make out anything. Can someone point me in a better direction for a solution to this problem?

transfering caller to another context without hanging up on bridge
by Michel Brabants 20 Mar '13

20 Mar '13

Hello, maybe a strange question, but is it possible to transfer the caller to another dialpla-extension, ... without hanging up an (almost) active bridge? Transferring to another context seems to hang up the bridge which was already established, but I would like to do some other actions while the bridge is active. Thank you and kind regards, Michel
