I want to install NM-HDV2-1T1/E1 on Cisco 3725 for VoIP using E1 which will be conectted to PBX.
But I am not sure which IOS Feature should be installed into 3725. ( current IOS is IP Plus)
IP Service is Enough ? or Need an Advanced IP Service ?
I tryed to search on Cisco Feature Navigater or Dynamic configuration tool .However , I can't find my requiring information.
Could you let me know how can I reach to the necessary information?
