<div style="word-wrap: break-word;">Juan,<div><br></div><div>I see your issue now.</div><div><br></div><div>Well, first solution is to only send to the provider the codec you want.</div><div>If you prefer G729 for a phone, it's likely the provider will support that, so offer only G729.</div>
<div><div>If you prefer PCM for another phone, it's likely the provider will support that, so offer only PCM.</div></div></div></blockquote><div><br>I think a parameter may be called 'outbound-codec-negotiation' would be a better solution. This way, when you will offer several codecs to the provider and the provider offer several codecs to you, you could set that your codec preferences have higher priority than the providers' as done with inbound calls.<br>

<div>When I sent them a list of codecs, my providers always replies with only one, the one they want, generally it's the first one in the list I offered.</div></div></div></blockquote><div><br>I suppose similar we offer several codecs to our registered ip phones.<br>
