(Optional) Configuring the SIP Call Bandwidth Limit on a NAT Device
Context
When the SIP server is deployed on the public network and SIP phones in public and private networks are interconnected, the call quality is affected if the bandwidth on the NAT device is insufficient. You can enable call admission control (CAC) and set the total bandwidth on the NAT device to limit the bandwidth of SIP calls. If the bandwidth of a SIP exceeds the specified value, the SIP call is rejected.
Procedure
- Run system-view
The system view is displayed.
- Run nat sip cac enable bandwidth { bandwidth-value | percent value interface interface-type interface-number [ .subnumber ] }
CAC is enabled and the total bandwidth is set to limit the bandwidth of SIP calls.
By default, the bandwidth limit is 0, indicating that the bandwidth is not limited.
