configure toll fraude prevention c880voice

[albertgascon]

Hello: I need to configure toll fraude prevention in three of my routers, Ios versions:

c880voice-universalk9-mz.124-24.T6.bin

c880voice-universalk9-mz.150-1.M8.bin

c880voice-universalk9-mz.150-1.M8.bin

I used the following guide, which according to Cisco, is intended for ios version 12.1 or later:

http://www.cisco.com/c/en/us/support/docs/voice-unified-communications/unified-communications-manager-express/107626-cme-toll-fraud.html

This is the configuration I planned to use, but my routers do not support any of the commands under "voice service voip",

Router> enable

Router# configure terminal

Router(config)# voice service voip

Router(conf-voi-serv)# ip address trusted authenticate

Router(conf-voi-serv)#ip address trusted call-block cause call-reject

Router(conf-voi-serv)# ip address trusted list

Router(cfg-iptrust-list)#ipv4 10.0.0.0 255.0.0.0

Router(cfg-iptrust-list)#end

I have been seaching for equivalent commands but haven't found any.

Is there anyone with experience configuring toll fraud prevention for devices with IOS release older than 15.1(2). What am I doing wrong?

Thanks in advance!

This feature did not exist pre 15.1(2). If you need it I suggest you upgrade your IOS. There is no concept of toll fraud prevention in older IOS releases

As Ayodeji suggested, it is recommended to upgrade the IOS for this feature.

Or esle, you can try configuring Access-Lists to block the traffic coming from un-wanted IPs
