Re: Whats coming with a Cisco 2811 voice bundle cisco2811-ccme/k
Yes with BRI you would be able to do that with just three circuits (is has two lines per circuit). The fax, you can use an ISDN NT1+ with pots ports, or can connect to router via FXS. You can have DID service with ISDN BRI and you have caller-id, plus protection for disconnection supervision problems that are very common with POTS.
You can do all that with the uc520, but you have to check with reseller if model UC520-32U-4BRI-K9 is available already, as cisco has initially introduced only the 8 and 16 users version.
IIf not uc520 use a 2811 with NM-CUE or AIM-CUE, the BRI is WIC2-2BRI-NT/TE. With that, you should also get a 2 or 4 ports FXS card to connect e.g. a wireless phones, fax, door-opener device, etc.
In any case you also need a PoE switch eg, that you can choose e.g. from express 500 24 ports.
Then there are the phones that you have not mentioned at all. A good purchase is the 7931G that has a lighted display and many buttons.
Note the feature of hunting an user when a call comes is not by default and can require additional configuration on the CME (router) or CUE (voicemail system).
