It has been a while since I did any heavy duty Cisco router config. Anybody know what the minimal IOS level requirement is for using a 2811 as a PRI gateway. The unit I have only has IP Base which is not letting me configure voice commands.
Here is a show hardware.
System image file is "flash:c2800nm-ipbase-mz.124-3f.bin"
Cisco 2811 (revision 53.51) with 251904K/10240K bytes of memory.
2 FastEthernet interfaces
24 Serial interfaces
1 Channelized T1/PRI port
DRAM configuration is 64 bits wide with parity enabled.
239K bytes of non-volatile configuration memory.
62720K bytes of ATA CompactFlash (Read/Write)
