Configuring cRTP Interfaces

The Avaya G250/G350/G450 Device supports RTP compression, reducing the overhead of
transmitting voice packets over the E1/T1 line. You can configure cRTP (Compressed RTP)
parameters for each PPP interface.
To define and display CRTP Interfaces:
Select IP Route > Header Compression> cRTP Interfaces. The cRTP interfaces window
opens.
