I am trying to find out if the 2800 series routers support clid / ani on the vic-2fxo interface or if a fxo-m1 is still required, and if so what the ETA for an IOS that supports that feature/hardware is due out, or if it already is released?
You will need the new VIC2-4FXO which does support CLID.
The old VIC-2FXO will not work at all (been there done that), so I doubt the m1 does either.
