A Bonus Disk is included with this Router!
The Disk includes all Software elements: CME 8.6, CCP 2.7, IP Communicator, IOS Images & dozens of IP Phone Firmware Files!
IP Communicator is a Software-based Phone (or Soft-Phone) that can be used to make actual phone calls.
You can even install IP Communicator on more than one PC and thus simulate a Phone Network without actual IP Phones!
Moreover, it supports multiple lines and directory numbers and therefore it can handle multiple calls!
The Disk also includes a Lab Exercise Guide (eBook in PDF format): CCNA Voice Lab Manual
With this Router you can implement a LAN-based Phone Network that can also make & receive Phone calls outside the LAN using the Voice Modules included with it.
To connect IP Phones to the CME Router you would need LAN Switch; if possible with PoE (Power over Ethernet) which would eliminated the need for Phone Power Supplies.
One port of the Switch would be connected to the Router's Ethernet interface, while the other ports would be used for the IP Phones.
Detailed configuration is needed in the Router (6 sections) in order to support SCCP & SIP Phones But this configuration has been already done on this Router!
So if you to add a PoE Switch and IP Phones, you'll be ready to start making phone calls!
No other Hardware is required to make calls between the Phones connected to the LAN!
