The number of ports ECS needs for this
purpose is the maximum calls allowed by
your license multiplied by four.
To limit ECS’s use of ports within the range
of 1024-5000:
1.
Close ECS.
2.
Open the registry.
3.
Navigate to HKEY_LOCAL_MACHINE\
SOFTWARE\RADVISION\
Enhanced Communication Server\
Storage\Config\Stack
4.
Create a new key of type REG_SZ called
PortMin. Give it the value of the
minimum port number ECS should use.
5.
Create a new key of type REG_SZ called
PortMax. Give it the value of the
highest port number ECS should use.
6.
Restart ECS.
There may be other applications on the
same computer which altered the global
maximum port for all processes running on
that Windows PC. Verify this global
maximum is unchanged in the
HKEY_LOCAL_MACHINE\
SYSTEM\CurrentControlSet\Services\
Tcpip\Parameters\MaxUserPort registry
key. If this key is not defined, its default
value is 5000.
