How to make calls from a computer to phones in a corporate network (cisco)?

Question

Cisco

What program can be used to call corporate numbers, cisco equipment installed, cost?

Answer 1

Cisco IP softphone, in my opinion, has already reached the status of EOL (end of life), I believe Cisco IP Communicator will help you . I can't comment on the price, unfortunately.
In case Cisco phones work in SIP mode, I assume a software SIP client will do.

Answer 2

cisco has great CUCM products as well as CUPC. There is a jabber client from which you can call anywhere. There is also an option to combine MS Lync with CUCM, then you can use Lync clients for calls.

Answer 3

Try contacting salespeople (but there is a subtlety - not everyone is qualified enough)
