[Freeswitch-users] Strange behaviour when sending to voicemail

[ocset]

Hi

I have a FreeSWITCH install that uses a Faktortel SIP gateway for 
incoming/outgoing calls. The gateway codec is g.722 and everything works 
fine except for redirection to voicemail. (I have hard coded the codec 
for the gateway since it would not work otherwise.)

Here is the conf/dialplan/public/01_line1.xml file with the dialplan for 
incoming calls

<extension name="line1">
<condition field="destination_number" expression="^(5555555555)$">
<action application="set" data="hangup_after_bridge=true"/>
<action application="set" data="continue_on_fail=true"/>
<action application="set" data="call_timeout=20"/>
<action application="bridge" data="group/sales@${domain_name}"/>
<action application="answer"/>
<action application="sleep" data="1000"/>
<action application="voicemail" data="default ${domain} 1000"/>
</condition>
</extension>

When the call is redirected to voicemail, half of the playback message 
is lost and the first thing the user hears is "to listen to the message 
press 1..."

If I change the dialplan to transfer to the "1000" extension instead, 
allowing FreeSWITCH to redirect to voicemail automatically when ext 1001 
does not answer, then voicemail works correctly.

Any suggestions?

Thanks
O.
