G729r8 to G711

Hello,

Is it possible to transcode 3 simultaneous calls from G729r8 to G711 without any DSP modules. I have Cisco 2811 , IOS 12.4(13r)T11, 2 x VWIC2-1MFT-T1/E1 cards. In other words how many calls can I transcode between this 2 codecs with Cisco 2811 internal resources?

Thank you.

Roman,

You need DSP for transcoding...

To know how many DSP you need you can use the cisco dsp calculator here..

Note: you need CCO login.

For the updated dsp calculator with PVDM3 , you can also access it here: http://www.cisco.com/go/tools --> Just look for DSP calculator

Also, you need PVDMs to enable those 2 VWICs assuming you're going to use them.
