The module to install for voice mail in the Cisco 2921 router

[Translator]

Good day,

I have a Cisco 2921 router, it has installed the module "PVDM3-32 V01" installed. The CME works without problem. I want to configure voice mail, it seems there is a module to install in the router. Can you help me identify the module I need to install for voice mail to work?

Best regards,

Good evening,

I want to thank you, I want to order the Cisco ISM-SRE (Internal Service Module-Services Ready Engine) module, as soon as I receive it there will be a new subject with the name "ISM-SRE module installation and configuration to enable voice mail"

Thank you
