Can a Cisco phone make calls via router to a residential phones

Example

10 cisco phones behind a CME router in a business to a residential phone in the outside world?

Do all connections need to be router based?

 

And how does an ISP communicate to a Cisco router using DID?

And does the ISP have to give certain information to the client in order for the clients Cisco phone calls to be connected?

You can configure a dial

You can configure a dial-peers as below for outgoing calls:

dial-peer voice 1 pots
 destination-pattern 9T       (this will route all calls to FXO and here 9 as a access code)
 port 0/1/2                           (this is port where FXO has connected at router)

You can refer below link and CME admin guide as well for further understanding.

To connect calls to outside

To connect calls to outside world basically you need to have some type of trunk (E1/T1/FXO/SIP Trunking) between ISP & CME router and when you will have this then you will get a DID from service provider and you can use these to connect with outside world's phones.

And for this you need to create dial-peers in CME to route external calls to trunk/ISP.

Hope this helps.
