PVDM MIM-2MFT

[dblank121]

Hello, for the ISR4331 do I need to install a PVDM64 on the NIM-2MFT to support voice?  I only have 7 phones and  a PVDM32 on the motherboard

Thanks

Hello @dblank121,

If you have a PVDM64 module installed on the NIM-2MFT card, it provides 64 voice channels for processing voice calls. With the PVDM64 module installed on the NIM-2MFT, you should have enough resources to support the voice requirements for your 7 phones.

Since each phone call typically requires one voice channel, and you have 7 phones, you will be utilizing 7 voice channels. The PVDM64 module on the NIM-2MFT provides a total of 64 voice channels, so it exceeds your current needs.

The number of voice channels required can vary depending on the codec in use. Ensure that you consider the bandwidth requirements of your chosen codec and the number of available voice channels on your PVDM module to determine if any additional hardware upgrades or changes are necessary. DSP calculator: https://dsp-calc.cisco.com/
