Latest version of FreeSWITCH has some updates that may fix this issue. I would update to 1.2.5.3 ASAP.<br>-MC<br><br><div class="gmail_quote">On Tue, Dec 18, 2012 at 1:56 PM, Yungwei Chen <span dir="ltr"><<a href="mailto:yungwei@resolvity.com" target="_blank">yungwei@resolvity.com</a>></span> wrote:<br>

<br>
I found one issue that voices are always out of sync in the recordings.<br>
I am running freeswitch-1.2.5.1-1 on CentOS 5 (i386), which was installed from yum.<br>
I am having trouble installing the latest version from source due to an error: Autoconf version 2.62 or higher is required.<br>
It would be nice if someone can reproduce this issue against HEAD. Thanks.<br>

Here're the steps to reproduce it. The idea is to call a phone number and then bridge to another phone number while the entire session is being recorded.<br>
1. In dialplan/public.xml, make sure you have a dialplan to handle any 10 digit phone numbers.<br>
<extension name="public_extensions"><br>
<condition field="destination_number" expression="^\d{10}$"><br>
<action application="transfer" data="main XML default"/><br>
</condition><br>
</extension><br>
<br>
2. In dialplan/default/main.xml, make sure you have an extension to handle the call in the default context.<br>
<extension name="test"><br>
<condition field="${destination_number}" expression="^main$"><br>
<action application="set" data="RECORD_STEREO=false"/><br>
<action application="answer" /><br>
<action application="record_session" data="/tmp/${strftime(%Y-%m-%d-%H-%M-%S)}_${destination_number}_${caller_id_number}.wav"/><br>
<action application="bridge" data="{ignore_early_media=false}[leg_timeout=60]sofia/gateway/gw1/1234567890"/><br>
</condition><br>
</extension><br>
<br>
3. In sip_profiles/external/gateways.xml, make sure you have a gateway that allows you to make an outbound call.<br>
<include><br>
<gateway name="gw1"><br>
<param name="username" value=""/><br>
<param name="password" value=""/><br>
<param name="realm" value=""/><br>
<param name="from-domain" value=""/><br>
<param name="extension" value=""/><br>
<param name="expire-seconds" value="60"/><br>
<param name="register" value="false"/><br>
<param name="retry-seconds" value="60"/><br>
</gateway><br>
</include><br>
<br>
4. make a call to one of the allowed 10-digit phone numbers in your environment.<br>
5. Once the call is answered, the caller shall start to count from 1 to 60 with some pause after each number.<br>
6. The callee shall repeat each number he/she heard from the caller.<br>
7. You should be able to hear that 2 voices in the recoridng (/tmp/rec.wav) are out of sync.<br>
