How to Simulate PSTN Using GNS3
This is my initial CCNA VOICE lab using GNS3. The most
important in this post is how to simulate the Public Switched Telephone Network
(PSTN). As you know currently GNS3 does not support FXS or FXO ports, so the
following configuration showing you how to get around this by Allah’s willing.
So, I have used the following IOS:
(C3745-IPVOICE_IVS-M), Version 12.4(15)T14
It is the same on all routers and the PSTN, this is to
decrease the processor load. Because as you know GNS3 uses the ghost image
feature which uses a single IOS on all routers from the same type instead of
using a dedicated image for each router.
