<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:

users. The Asterisk box uses a SIP provider for placing external calls and
receiving incoming calls as well. In other words, there’s no PSTN or ISDN
lines attached to the box. Codec in use is G.711 alaw.<o:p></o:p></span></font></p>

Sound files are the standard moh mp3s. When I call the queue from local sip
clients everything works fine, I hear the music and all seems well. However, if
I call from a landline to the asterisk box through the SIP-provider, I can only
hear the music whenever I am talking to myself, making some noise etc. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>I figure it has something to do with silence
suppression, but wherever I search I only find information on how to disable
this on SIP clients. Since this is a problem that arises somewhere between the
SIP provider and the asterisk box, I am lost. Is there any way to get around
this in the asterisk configuration, or is it simply that the SIP provider itself
is refusing to transmit comfort noice?<o:p></o:p></span></font></p>
