router(config)#voice-card 1
router(config-voicecard)#codec complexity ?
flex Set codec complexity Flex. Flex complexity, higher call density.
high Set codec complexity high. High complexity, lower call density.
medium Set codec complexity medium. Mid range complexity and call density.
secure Set codec complexity secure.

When you use flex complexity, up to 16 calls can be completed per DSP. The number of
supported calls varies from 6 to 16 and is based on the codec used for a call. Also notice
the secure option, which supports Secure RTP (SRTP). SRTP secures voice streams by
providing authentication and encryption services to RTP.
The show voice dsp command, as demonstrated in Example 2-3, can be used to verify
codec complexity configurations.
