The Cisco 887 VA-V and Cisco 881-V routers give you the flexibility to use the FXS or BRI voice ports (The

Cisco 881-V router also supports a backup FX0 port), but the number of concurrent calls that the router

supports is limited by the codec complexity configuration. The router supports less calls when the codec

complexity setting is configured for high complexity. Table 7: Number of Concurrent Calls Supported on

Cisco 880 Series Data and Voice ISRs, on page 7 shows the number of concurrent calls that is supported

on the router for each codec complexity setting. Configuring the codec complexity setting to support secure

calls does not affect the numbers below.
