Figure 1-13, Figure 1-14, and Figure 1-15 show the features available on the Cisco 881-V and

Cisco 887VA-V routers. The features available vary, depending on the router model. Some features may

not be available on your router.

The Cisco 881-V and Cisco 887VA-V voice and data series gives you the flexibility to use either FXS

or BRI voice ports. However, the number of concurrent calls that can be supported by the router is

limited by the codec complexity setting on the router.

Table 1-3 lists the maximum number of calls that

is supported when the codec complexity command is configured for Flexible, Medium or High

complexity.
