Settings for the HiPath Provider on HiPath 3000/4000/5000
> Activate the Teleworking option if you work at a teleworkstation. To reduce the data
volume or bandwidth requirements via the trunk, activate the options Voice compression
and Suppress cyclical control message. These options are activated automatically
when the Teleworking option is enabled at Logon.
> Communication between optiClient 130 and the communication system is based on
defined compression algorithms for the network transmission of audio signals (codecs).
Under Codec sequence you can define the desired sequence sequence of the codecs to
be used for the voice connection. A different selection is made available on activating the
Teleworking option.
> The respective voice packet lengths for the codecs G.711, G.723 and G.729 are defined
under Codec packet lengths individually by specifying the number of milliseconds.
> To avoid jitter in the network (arising from variable delays), you can define the size of the
jitter buffer under Jitter-Buffer (packet number). The following generally applies for an
optimum setting: the better the network quality, the smaller the jitter buffer can be, and the
larger the jitter buffer, the greater the voice delays. The buffer size can be set to between
4 and 20; the recommended value is 6.
10.1.8 Port Restriction Settings

ments.

> Port 4060 is used by default on the communication system gatekeeper for the CorNet
connection. You can specify a port area for the local PC. The option CorNet port range
from must be activated, and the port numbers from/to must be entered so that the set port
range is used. If you do not activate the option, any port on the PC assigned by the
operating system is used.
> The communication ports used for signaling (H.245 ports) and voice connections (RTP
ports) are defined by activating the option RTP port range or H.245 port range and
entering a "port range from/to".
