[SHERDILKHAN2017]

Can any one tell me whats the difference between ISR4431/k9 and ISR4431-V/K9?

"-V" = VOICE.

"V" like voice is clear. But which components are inlcuded ?

- 64-channel DSP module or 32-channel-DSP  ?

- anything else included in -V bundle ( ISR4431-V/K9 ) vs. non-bundle ( ISR4431/K9 only )

For voice deployment, mabye are these following parts needed or recommended as well:

• Cisco Communication Manager Express (CME) - 1 User License
• Cisco SRST - 1 SRST Endpoint License
• CUBE - 1 Standard Trunk Session License
• Network Interface Modules – Voice
