If you want Speex support you need to target the chipset manufacturers:<div><br></div><div>Here is the Texas Insturments chipset that Polycom uses in the IP650</div><div><span class="Apple-style-span" style="font-family: 'Times New Roman'; font-size: 16px; "><pre style="word-wrap: break-word; white-space: pre-wrap; ">
CPU is TNETV1050/C55x, rev 2 running at 162MHz with memory at 125MHz.</pre><pre style="word-wrap: break-word; white-space: pre-wrap; ">And here are the codecs that Chip supports from TI's datasheet on this chip:</pre>

Codec Options*

<div><br></div><div>I'm willing to bet that Cisco doesn't make their own DSP chips either. Find out who makes their chips and put pressure on that chip manufacturer to develop chips with Speex support.</div><div><br>

</div>Yeah.. let me know when you get Cisco to add Speex support to IOS! ;)<br>
