Which module fits my router?

Router generation decides most of it. The EtherSwitch and digital voice modules here are network modules for the 2800 and 3800 Series ISRs, and Cisco also lists the voice module for the 2600XM, 2691 and 3700 Series. Cisco states that the NME-X-23ES-1G-P is not supported in 2900 or 3900 Series routers, and Cisco's platform table for the NM-HDV2-2T1/E1 stops at the 2800 and 3800 Series. For the NME-UMG-EC, Cisco's data sheet lists the 2800 and 3800 Series and, with an adapter, the 2900 and 3900 Series.

Does the EtherSwitch module need a particular router power supply for PoE?

Yes. The NME-X-23ES-1G-P supports IEEE 802.3af and Cisco pre-standard PoE, and Cisco states that the AC-IP power supply is required on 2800 and 3800 Series routers to use it.

How much voice capacity does the NM-HDV2-2T1/E1 have?

It has two built-in T1/E1 controllers and four PVDM2 sockets, which Cisco says support up to 16 onboard DSPs with four PVDM2-64 cards. Adding VWICs can raise the total to four T1/E1 voice controllers. Check the listing for which PVDMs, if any, are installed.

What does the enhanced-capacity UMG module add?

Cisco lists the NME-UMG-EC at up to 1,000 Cisco Unity Express endpoints per module, against 250 for the standard NME-UMG, with 2 GB of RAM instead of 1 GB.
