Preferred Rtp Data Payload Type | The RTP Payload Type included in the RTP header of the data packet. The value ranges from 0 to 127 and the default value is 56. | |||||||||||||||||||||||||||||
Initial Playout Buffer Delay | Used for G.711 only. This is the initial playout delay for calls with a data bearer channel, for example, ISDN 64K data calls. This value is configured separately from the initial playout delay for voice channels (Voice Initial Playout Buffer Delay) so providers can trade off delay on data calls versus the likelihood of jitter causing delay changes while the playout buffer adapts. Some data bearer calls are very sensitive to delay changes (such as H.320 video conferencing), so a higher initial delay should reduce the chance of jitter bursts causing problems.

The SBC as part of media lock-down may send a re-INVITE to egress peer. Note that the preference on the answerer side is given to a pass-through codec. |
enable | enable | The SBC gives preference to HAP over HOP in case of conflict. The Honor Remote Preference (HRP) flag on the answerer leg decides the preference order. Based on that preference list, the SBC selects a codec with highest preference from answer SDP that can be used even if it requires transcoding. Note that this may cause the selection of a codec on the other side leg not to be honored. This happens in case of a pass-through call. |

...
Enable flag to generate a new SSRC (using a random value) along with a new time stamp on a new RTP stream whenever a resource is reactivated (due to change in codec, etc.). SSRC randomization reduces the probability of collision in large groups and simplifies the process of group sampling that depends on uniform distribution of SSRCs. The options are:

Low Speed Number Of Redundant Packets | This field specifies the number of redundant IFP messages sent in a UDP packet for T.38 low speed fax transmission, and applies only if the T.38 error correction type is redundancy. (range: 0-2 / default = 1). |

maximum bit rate which controls and manipulates bits 11, 12, 13, and 14 in the DIS command received by the SBC from either the TDM circuit interface or the T.38 packet interface:

Number Of Redundant Packets | Use this parameter for high-speed fax relay to specify the number of redundant Internet Facsimile Protocol (IFP) messages sent in a User Datagram Packet (UDP) for fax transmission. (range: 0-2 / default = 1). |

Video Calls | |
---|---|
Max Video Bandwidth | The maximum allowable session bandwidth (in Kbps) for a call that includes video streams. This value includes the bandwidth for all streams in the call (audio, video, BFCP, and so on). If "0" is set as the value, video calls are not allowed; and only audio calls can be set up following the normal allocation process (range: 0-50000 Kbps / default = 10). |
Video Bandwidth Reduction Factor | The amount, as a percentage, to reduce the session bandwidth allocation for calls that include video streams. This setting only affects the internal allocation of bandwidth used for the calls (does not affect the signaling). For example, if the reduction factor is "20", the bandwidth allocated for calls is reduced by 20%. In other words, if the normal bandwidth allocation for calls is 1000 Kbps, a 20% reduction equates to a new 800 Kbps bandwidth. (range: 0-100 / default = 0). |
Ipv4Tos | IPv4 type of service. (range: 0-255 / default = 0). |
Ipv6Traffic Class | IPv6 traffic class. (range: 0-255 / default = 0). |
...
|
...
| |
Ieee8021QVLan Cos | IEEE-802 1Q VLAN Class of Service. (range: 0-7 / default = 0) |
Codec List Profile | Name of the Codec List profile used to store precedence and purge lists of video codec MIME subtypes. |
Audio Only If Video Is Prevented | By default, this |
...
option is enabled to allow a call to continue with the audio portion only |
