Parameter |
Values |
Description |
Offer Ptime |
10 20 30 (Default: 20) |
Length of time in milliseconds represented by the media in a packet offered by the PowerMedia WMS in the SDP attribute (a=). This setting applies when the inbound initial INVITE does not contain an SDP body, forcing the PowerMedia WMS response to make the initial SDP offer. |
Jitter Buffer Max Size |
Integer: 6 to 10 (Default: 6) |
Maximum size of jitter buffer. |
Jitter Buffer Nothing Read Depth |
Integer: 3 to 20 (Default: 3) |
Value used to insert silence in the packet stream. If no packets are read from the line, then audio silence is inserted in the RTP stream. |
Default Ulaw Ptime |
10 20 30 (Default: 20) |
Value to use when the SDP offer is received, but the PTIME attribute is not specified. This value appears in the SDP answer sent by the PowerMedia WMS. |
Default Alaw Ptime |
10 20 30 (Default: 20) |
Value to use when the SDP offer is received, but the PTIME attribute is not specified. This value appears in the SDP answer sent by the PowerMedia WMS. |
Default G726 Ptime |
10 20 30 (Default: 20) |
Value to use when the SDP offer is received, but the PTIME attribute is not specified. This value appears in the SDP answer sent by the PowerMedia WMS. |
Default G729 Ptime |
10 20 40 (Default: 20) |
Value to use when the SDP offer is received, but the PTIME attribute is not specified. This value appears in the SDP answer sent by the PowerMedia WMS. |
Offer AMR Payload |
Integer: 96–127 (Default: 96) |
Dynamic payload type to be used when AMR is offered. |
Default AMR Ptime |
20 40 (Default: 20) |
Value to use when the SDP offer is received, but the PTIME attribute is not specified. This value appears in the SDP answer sent by the PowerMedia WMS. |
Default AMR Alignment |
Bandwidth-Efficient Mode (bit) Octet-Aligned Mode (byte) |
Default alignment mode to be used when INVITE SDP specifies AMR encoding, but does not specify the alignment mode. |
Offer AMR Octet Align |
Bandwidth-Efficient Mode (bit) Octet-Aligned Mode (byte) |
Alignment mode to be used when AMR is offered. |
Offer AMR Mode |
AMR 4.75 AMR 5.15 AMR 5.9 AMR 6.7 AMR 7.4 AMR 7.95 AMR 10.2 AMR 12.2 |
Default AMR-NB encoding mode (bit rate). |
