VoIP authentication

Hi there,

we have been trying to set up AAA using our AS5300 and the Cisco Secure ACS to handle who may call international calls and who may not. As our customers are using phones to connect and make international calls we have to use their caller id to check if they are allowed to call or not.

We are pretty sure that we have configured the Ciso Secure ACS the right way. But we are not as sure about the configuration on the gateway (AS5300). For some reason it is not sending any packets to the Cisco Secure ACS.

Does any of you have any experience in this that you are willing to share with us or can you point us to some good documentation for case like this.

Is it possible that we have to use some special IOS and avoid some others. We are using 12.1(5)T. We are also using Cisco Secure ACS 2.4(1)

Thanks in advance,

Re: VoIP authentication

I don’t think anyone can help you without looking at your configs and troubleshooting some things. I’d suggest calling your Cisco rep and getting one of their security specialists to take a look at your setup.

Re: VoIP authentication

If you are not seeing any traffic to your acs server, including no failures in the acs logs, you might want to check to make sure that the 5300 & the acs server are using the same ports for radius authentication and accouting (1645 & 1646 / 1812 & 1813).
