i have a cisco 2811 with ios Version 12.4(13r)T. i used this router for voice gateway. now i have added another ethernet card into this router,and i would ask if there is a ios version that have a both functionality ( voice + firewall.).
Most likely router was shipped with SP services, but it may have just the voice feature set. Either one has the same solution. Changing the IOS version is accomplished by ordering:
28N-SW-SPARECD - Cisco 28N Series Software Spare CD
S28NAISK9-12415T - Cisco 2800 ADVANCED IP SERVICES.
This will bring you up to Advanced IP services which has both voice and security features.
Be aware that this recommendation is based on the information provided. To ensure that you get the right IOS, I would recommend that you work with a Cisco partner and provide them a show inventory from your router to ensure the IOS chosen will support all of your cards.
Your show version indicates that you have Service Provider services. You don't seem to have any special cards that would require a special release train, so Advanced IP Services would most likely work. Here is a link to a chart in Figure 1 that provides a good overview of which IOS feature sets do what.
