Setting Description
Maximum Transmission Unit Size Bytes Specifies the MTU size (in bytes) used in calls.
▪ If video quality is poor or you experience
network errors, packets might be too large.
Decrease the MTU.
▪ If the network is burdened with unnecessary
overhead, packets might be too small. Increase
the MTU.
Enable Lost Packet Recovery If you enable this setting, the system uses the Lost
Packet Recovery (LPR) protocol to help
compensate for packet loss if it occurs.
Enable RSVP If you enable this setting, the system can use the
Resource Reservation Setup Protocol (RSVP) to
request that routers reserve bandwidth along an IP
connection path. (To use this feature, the near and
far site must support RSVP.)
Dynamic Bandwidth Enable this setting if you want the system to
automatically determine the optimal call rate.
MRC Bandwidth Allocation Adjusts media bit stream bandwidth, reducing
packet loss.
Maximum Transmit Bandwidth Specifies the maximum transmit call rate between
64 kbps and the system’s maximum line rate.
Use this setting when the system connects to the
network using an access method with different
transmit and receive bandwidths.
Maximum Receive Bandwidth Specifies the maximum receive call rate between
64 kbps and the system’s maximum line rate.
Use this setting when the system connects to the
network using an access method with different
transmit and receive bandwidths.
3. Select Save.
Configure H.323 Settings
If your network uses a gatekeeper, the G7500 system can automatically register its H.323 name and
extension. This enables others to call the system by entering the H.323 name or extension instead of the
IP address.
Procedure
1. In the system web interface, go to Call Configuration > H.323.
2. Configure the following settings:
