There are some articles already in this site covering topics from. In this one I’ll present a GNS3 lab with a very good SCCP (Skinny Client Configuration Protocol) softphone which makes a lot of experimenting possible as it provides more e-phone devices on one computer.

We can configure phone settings, call forwarding, dial peers and other things more easily than with the Cisco IP Communicator, as it allows only one instance per PC. The software is called VTGO-PC Multilab from IPBlue Software. You can download it here:. VTGO-PC Multilab allows us to use up to five e-phone instances which behave like Cisco IP Communicator or a real 79xx series IP phone. We’ll use the unregistered version which has restrictions on the duration of the calls and session length. In lab environments, those are not too important.

Installation guidelines for MultiLab pilot software (1) The first step is to download and install the MultiLab pilot software from our homepage. You can run the MultiLab pilot with e.g. Lab 860 as anonymous or as administrator. 05411792 is the serial number and the program also recognizes the device.

The base topology is as follows: The phone objects are clouds which connect to Loopback interfaces on the host PC. We can create and manage the loopbacks from GNS3 (under the Tools/Loopback manager menu) and give them a static IP address from the 172.16.1.0/24 network. I changed the symbol to reflect that the connected devices are phones and indicated the addressing scheme also. Another way to place phone devices is to use the Edit/Symbol manager: select the ip_phone from the Available symbols and move it to the right panel by clicking “>”.

Then in the upper right corner change the name to “IP Phone” and the type to “Cloud.” One more important note is to use an IOS which supports voice. I used 2600 series routers with the Advanced IP Services feature set. First we need to configure the phone instances with the Setup Phones Wizard: As can be seen we need to configure the TFTP server’s IP address, the MAC addresses of the phones (I used these ones for easy management) and the phone type.

Before launching the softphones, let’s configure the CME1 router by the telephony-service setup command. The relevant questions and answers of the wizard are as follows: When this part is complete, we have a common configuration file called XMLDefault.cnf.xml stored in RAM, specifically in the system:/its directory. During the booting process, the softphones will search for this configuration file, but in order to provide it for the softphones, we have to do some work. First, copy this XML file to Flash with the following command: copy system:/its/XMLDefault.cnf.xml flash:SEP01.cnf.xml The command asks to erase the Flash: let it do this. The softphones will search for a configuration file under a special name: the SEP prefix means Selsius Ethernet Phone, followed by the MAC address of the phone. Repeat this for the second and third phone also, but now of course don’t let it erase the Flash, which will now contain three XML files.
