Voice Services Interfaces Operational Mode Command

This chapter describes the show interfaces command you use to monitor and troubleshoot voice services interfaces.

The Adaptive Services PIC supports the compressed real-time transport protocol (RTP) on the interface type vsp-fpc/pic/port. This protocol enables voice over IP (VoIP) traffic to use low-speed links more effectively, by compressing the 40-byte IP/UDP/RTP header down to 2 to 4 bytes in most cases.
