I have a Cisco 2811 router w/ IOS version 12.4(9)T1 SPSERVICESK9, configured with a VWIC-1MFT-E1.
I'm drop-in replacing an existing Cisco 2600 router with the 2811. The site runs Cisco IP Phones w/ SRST configured using an E1 PRI connection.
Because I want to do a straight drop-in replacement, I've pretty much copied the existing voice configuration verbatim. However, when I get to the "voice-port" command, the router complains - there's no "voice-port" command available to me.
Looking at the original router, it has an NM-2V network module installed (which is hardware incompatible with the 2811 *doh*). I haven't bought an equivalent NM-HD-2V for this router yet, and am suspecting the following:
* The NM-HD-2V network module provides the "voice-port" command ability; or
* I have the wrong IOS image installed on the 2811 router.
Also, can someone please tell me the difference between an NM-HD-2V, and an NM-HDV2, apart from the fact that the HD-2V network module provides 2 x VWIC slots, and the HDV2 module doesn't?
I look forward to your replies.
