[cisco-voip] Transcoding

[Ryan West]

David,

Check out the PVDM2's for use with ISR's.

Depending on the size of the router you can load between 128 and 256 worth of calls using g711. Divide by 2 for g729.

Thanks, Ariel.
So I still need the DSP card NM-HDV2 (IP Communications High-Density Digital Voice or Fax Network Modules for the Cisco 2600XM/2691/2800/3700/3800 router platforms).
I saw the largest one is NM-HDV2-64 which can only provide 32 calls with G.729 codec.

How many NM-HDV2 can a C37xx/28xx load?
Comparing with AS5400+NP108, which one is better?
Thank you.

David

David,

    You should use the DSP Calculator to estimate how much DSP resources you will need for transcoding

Hi folks,
Does anyone familiar with the transcoding feature on 26xx/28xx/38xx?
I want to translate 150 calls to G.729 fromm G.711, what's the minimal hardware requirement?

Thanks!

David
