Table 5-15 Media Stream Configuration Parameters
Name Description
Min. RTP port
The minimum value of UDP ports for RTP transmission and receiving, and the parameter
must be greater than or equal to 3000.
The value is recommended to be equal or greater than 10000.
Note: each phone call will occupy RTP and RTCP ports.
Max. RTP port
The maximum values of UDP ports for RTP’s transmission and receiving.
It’s advisable to be greater than or equal to “2× number of lines + min. RTP port”.
iLBC payload type
Set the RTP payload type of iLBC, and the default value is 97. Accepted value is 97-127.
The parameter shall be configured in conformity to that of platform.
G.723.1 rate
Set G.723.1 coding rate
，
the default value is 6300. The optional parameters are followings:
5300: the Bit rate is 5.3k per second;
6300: the Bit rate is 6.3k per second
TOS bits
This parameter specifies the quality assurance of services with different priorities. The
factory setting is 0x0C.
For example, TOS=0xB8 indicates that the priority of the service quality is 5, with a
requirement on low delay and high throughput. There is no requirement on the reliability.
Min. Jitter buffer
RTP Jitter Buffer is constructed to reduce the influence brought by network jitter. This
default value is 3.
Max. Jitter buffer
RTP Jitter Buffer helps to reduce the influence brought by network jitter. The default value
is 50.
RTP drop SID
Determine whether to discard received RTP SID voice packets. By default, SID voice
packets will not be dropped.
Note: RTP SID packets should be dropped only when they are in unconformity to the
specifications. Nonstandard RTP SID data could generate noise for calls.
Enable VAD
Only applicable to G.723, GSM, iLBC. In case of selecting this parameter, it will not send
any voice packet during mute period. By default, this is selected.
RTP destination address
This parameter determines where to obtain the IP address of the receiving side for RTP
packets. By default, the IP address is obtained “From SDP global connection”.
From SDP global connection: Obtain the IP address from SDP global connection;
From SDP media connection: Obtain the IP address from SDP Media Description.
