Hi ,<br><br>Do you have issues only with hearing the IVR originating from the switch ? <br>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?<br>
Your voice mail gets recorded properly means the RTP is passing well to the switch ...<br><br>Regads<br>Sam<br><br><br><div class="gmail_quote">On Sat, Dec 18, 2010 at 2:52 AM, Rafqat . <span dir="ltr"><<a href="mailto:rafonline@hotmail.com">rafonline@hotmail.com</a>></span> wrote:<br>

<div class="h5"><br><br>
<br><br>Hi, <br><br>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.<br>
<br>Is this an issue with my phones (Flexor 500)? I have a softphone which doesn't seem as bad but still has issues.<br><br>I also get the following message on startup of freeswitch:<br><br>2010-12-17 21:17:39.138958 [WARNING] switch_time.c:206 Timer resolution of 4000 microseconds detected!<br>
Do you have your kernel timer frequency set to lower than 1,000Hz? You may experience audio problems.<br><br>I assume its related. <br><br>Any help will be much appreciated.<br><br>Cheers<br><br>Raf<br>
