"Error: 488: not acceptable here" in officesip (uses uccapi)
<p>I am developing a softphone,using "officesip (<a href="https://sourceforge.net/projects/officesip/" rel="nofollow">https://sourceforge.net/projects/officesip/</a>)", I succeeded in establishing call between subscribers, but while a receiver picks up the call the, the call is terminated,showing "error:488:not acceptable here".</p>

<p>At sender side, I found that the  error is related to media compatibility issue. But I couldn't find how to solve it, where do I need to configure or change?</p>

<p>Notes:   </p>

<ol>
<li><p>I have only headset connected to my PC no webcams</p></li>
<li><p>SIP server is NGCP-SIPWISE</p></li>
<li><p>The call works perfectly when I call from "officesip" to "X-lite",but terminates when I call between two "officesip",after receiver picks up,with status 488.</p></li>
