AVAYA Avaya Solution amp Interoperability Test Lab Configuring Juniper Networks J4300 and Cisco 1841 Routers to use compressed Real Time Protocol over Point to Point Protocol to Support an Avaya IP Telephony Infrastructure Issue 1 0 Abstract These Application Notes describe the steps for configuring Juniper Networks J4300 and Cisco Systems 1841 routers to use compressed RTP cRTP over a Point to Point Protocol PPP connection to support an Avaya IP Telephony infrastructure The Avaya IP Telephony infrastructure consists of Avaya Media Server Avaya Media Gateways and Avaya IP Telephones The Juniper Networks and Cisco routers will perform header compression for all RTP packets traversing over the PPP connection to minimize overhead and increasing available bandwidth AL Reviewed Solution amp Interoperability Test Lab Application Notes 1 of 20 SPOC 8 16 2006 2006 Avaya Inc All Rights Reserved J C cRTP PPP doc 1 Introduction RTP packets generated by Voice over IP VoIP telephony are typically small in size ranging in tens of bytes per packet Various headers such as IP 20 bytes and UDP 8 bytes are then added onto each packet before transmission Because of the relative small packet size of RTP packet the IP and UDP headers compose a large percentage of overhead in each frame For RTP packets that traverse a Wide Area Network WAN that has a small bandwidth The IP and UDP headers represents an opportunity for ban
