<div>Hi,</div>
<div> </div>
<div>I have two asterisks that are connected to each other via a back-to-back E1 link using a pair of sangoma cards. </div>
<div> </div>
<div>With the following scenario: SIP-PHONE <-> Asterisk <-> E1 <-> Asterisk <-> SIP-PHONE, the sound quality degrades significantly. I can't understand why as the amound of packet lost should be very minimum.</div>
<div> </div>
<div>Does anyone know why? Does it have anything to do with what codec to use?</div>
<div> </div>
<div>Thanks, </div>
<div>Mark</div>
