Depends on the complexity, which in turn dictates what codecs can be used:<br><br><a href="http://www.cisco.com/en/US/docs/routers/access/1700/1751/software/feature/guide/dsp_cn.html#wp70832">http://www.cisco.com/en/US/docs/routers/access/1700/1751/software/feature/guide/dsp_cn.html#wp70832</a><br>

Thanks a lot for the link man, but according with the DSP Calculator, this relationship is correct?<br>
<br>
1 PVDM2-8 (1 DSP) has 8 voice channel to g711.<br>
1 FXS/FXO port needs two voice channel (1 for TX and the other 1 for RX)<br>
then<br>
1 PVDM2-8 can support 1 VIC2-4FXS<br>
<br>
Thanks for your answer<br>
David<br>
