[asterisk-users] Cisco router

[Jonathan Thurman]

Depends on what the router is.  If you get a 2800 series router (we
use 2801s and 2811s for T1s in production with no major issues).  You
need the T1/E1 module, DSPs, and an IOS that supports voice.

For a 2800 series you would need something like:
 - VWIC2-MFT-T1/E1 ( or VWIC2-2MFT-T1/E1 if you want two ports)
 - PVDM2-32 (PVDM2-64 if you want two E1 ports, or two PVDM2-32s)
 - IOS that supports voice (I use spservicesk9)

If you are looking at an older router like a 2651XM or something, you
will need something like:
 - NM-HDV2-2T1/E1 (not the VWIC2, as the NM has build in ports)
 - PVDM2-32

If you have a specific router in mind, I can be more specific.
