Installing CallManager Express in GNS3
This article describes how to transform a Cisco router in GNS3 into a Cisco CallManager Express or CUCME.
Remember that a Cisco router can become a CallManager Express if we install the CUCME package into it.
I’ll assume you have a CUCME package on your computer.
Here is the setup in GNS3:
- a router destined to become CUCME
- a cloud item associated to the physical network card of the host machine
- a link between the router and the cloud.
We also need a TFTP server software. One of the best free TFTP servers is TFTPD32.
After you build the topology in GNS3, configure the router:
- set up the FastEthernet interface for connectivity with the host machine network. The host machine NIC address is 10.11.14.2. The router’s FastEthernet IP address is 10.11.14.254:
- Erase the router Flash:
- And format it:
To the TFTP server now. Download and install the TFTP server.
Set it up in a way that it points to a directory that contains the CUCME file.
On the GNS3 router, with the archive command:
- copy the CUCME tar file from the TFTP server to Flash,
- extract the files from the CUCME tar file.
After the operation terminates, you do a show telephony-service to display the CUCME version:
