Cisco 881 chassis - more than 5 vty lines possible?

Hi

Can someone please tell me whether it is possible to have more than 5 vty
lines on Cisco 881 chassis?

See below, it only shows upto 5 but I wonder whether it is a hardware
limitation or software (licensing) limitation on 881 chassis.

R1(config)#line vty ?
  <0-4> First Line number

R(config)#
R1(config)#do sho ver | in Cisco IOS
Cisco IOS Software, C880 Software (C880DATA-UNIVERSALK9-M), Version
15.0(1)M5, RELEASE SOFTWARE (fc2)
R1(config)#
