Cisco Voice Voice Peer Configure Session Target

1.3.6.1.4.1.9.9.63.1.2.2.1.1

The object specifies the session target of the peer. Session Targets definitions: The session target has the syntax used by the IETF service location protocol. The syntax is as follows: mapping-type:type-specific-syntax the mapping-type specifies a scheme for mapping the matching dial string to a session target. The valid Mapping type definitions for the peer are as follows: loopback - Syntax: loopback:where 'where' string is defined as follows: compressed - loopback is performed on compressed voice as close to the CODEC which processes the data as possible. uncompressed - loopback is performed on the PCM or analog voice as close to the telephony endpoint as possible. Local loopback case: uncompressed - the PCM voice coming into the DSP is simply turned around and sent back out, allowing testing of the transmit--> receive paths in the telephony endpoint. compressed - the compressed voice coming out of the CODEC is turned around on the DSP module and fed back into the decompressor through the jitter buffer. In addition to the telephony endpoint, this tests both the encode and decode paths without involving data paths or packet handling on the host router. Remote loopback case: compressed - RTP packets received from the network are decapsulated and passed to the DSP board. Instead of feeding these into the CODEC for decompression, they are immediately sent back to the session application as if they had originated locally and been compressed. uncompressed - In addition to the above, the voice samples are sent all the way through the CODEC and then turned around instead of being sent to the telephony endpoint
