Try using a IVR sound file with 64kbps instead of 128kbps and check. Regds Sam On Mon, Dec 20, 2010 at 12:20 AM, Rafqat . <rafonline@hotmail.com> wrote:
Hi Sam
Sorry for the late reply.
My issue is with only hearing the IVR originating from the switch.
Phone call debug:

The phone when playing 'vm-enter_id.wav' seems to jump in volume (initially low volume then high). It also makes a high pitch creaking type noise after 'say:[#] '.
Also when it asks me to leave a message after the tone, it immediatley says 'my message was too short' without allowing me to record anything. Could the phone be sending an echo which causes freeeswitch to think i have ended my recording?
I was wondering if i should invest in some new phones? Any recommendations?
Cheers
Raf

Hi ,
Do you have issues only with hearing the IVR originating from the switch ? Phone to phone works fine when RTP pass through is enabled ? which codec gets negotiated when IVR plays and what are the IVR file properties which is negotiated? Your voice mail gets recorded properly means the RTP is passing well to the switch ...

btw. I have no audio issues when making calls between phones through freeswitch (voice quality is very good).

Hi,
I recently installed freeswitch 1.0.6 on centos 5.5 (hosted on xen server). I feel as if the audio quality is not as good as what it should be (6-7 out of 10). This is apparent in calling the default voicemail IVR, sometimes I have issues leaving a message, sometimes I hear some weird noises. However, I have no issues with the quality of the recorded voicemail message I leave, it sounds fine on playback.
Is this an issue with my phones (Flexor 500)? I have a softphone which doesn't seem as bad but still has issues.
I also get the following message on startup of freeswitch:
2010-12-17 21:17:39.138958 [WARNING] switch_time.c:206 Timer resolution of 4000 microseconds detected! Do you have your kernel timer frequency set to lower than 1,000Hz? You may experience audio problems.
I assume its related.
Any help will be much appreciated.
Cheers
Raf
