2-rtp-pkt-loopback, the RTP payload is re-encapsulated and the RTP packets are looped back with a
new payload type and format. This type of loopback applies to the encapsulated and direct packet
loopback. Any type of encoding-related functions must not be part of this type of loopback path.
3-rtp-media-loopback & rtp-pkt-loopback, the answer must include only one of these two loopback
types and should give preference to the first loopback-type in the SDP offer.
Default
3
Parameter
sip.pkt_loopback_mode <y0000000000xx>.cfg
Description
It configures the encapsulation mode of incoming RTP packet.
Note: It works only if “sip.loopback_type” is set to 2 (rtp-pkt-loopback).
Permitted
Values
1-encapsulated packet loopback, the entire incoming RTP packet is encapsulated as payload within
an outer RTP packet. The loopback source can generate statistics for one-way path performance up
to the RTP level for each direction of travel.
2-directed packet loopback, the loopback mirror copies the payload of the incoming RTP packet into a
new RTP packet. The packet source can compute only two-way path statistics from the direct loop-
back packet header.
3-encapsulated & directed, the loopback mirror loops back the incoming RTP packets using either the
encapsulated RTP payload format or the direct loopback RTP payload format.
Default
3
Parameter
sip.pkt_loopback_encapsulated_payload <y0000000000xx>.cfg
Description
It configures the value of dynamic payload for encapsulated RTP.
Note: It works only if “sip.pkt_loopback_mode” is set to 1 (encapsulated packet loopback).
Permitted
Values
Integer greater than 98
Default
112
Parameter
sip.pkt_loopback_directed_payload <y0000000000xx>.cfg
Description
It configures the value of dynamic payload for the direct loopback RTP.
Note: It works only if “sip.pkt_loopback_mode” is set to 2 (directed packet loopback).
Permitted
Values
Integer greater than 98
Default
113
Parameter
sip.loopback.auto_answer.mode <y0000000000xx>.cfg
Description
It enables or disables the phone to automatically answer the incoming loopback call.
Permitted
Values
0-Disabled
1-Enabled
Default
1
Cloud
Yealink CP920 phones support cloud feature. The Cloud enterprise administrator uses the Yealink VC Cloud man-
agement service to assign each user an individual Cloud account. For more information, refer to Yealink VC Cloud
Management Service Administrator Guide .
After registered with a Yealink Cloud account successfully, the phone will download the Cloud accounts information
from the server automatically.
