Voice compression
Adjust the desired compression of voice data with this setting. Please note that the
voice quality can deteriorate. In addition, the compression you have selected has to
be supported by the Internet telephony provider and by the terminal.
Registration interval
The registration interval is the span of time that passes until the device re-registers
with your Internet telephony provider.
If you have a DSL provider that performs a forced disconnect once a day and your
DSL modem assigns a new IP address, you should enter a small value for the
registration interval. In the time between the forced disconnect and a new registration
it is possible that you cannot be reached by VoIP and that you cannot make any VoIP
calls.
Overview of settings for the selected provider
If you click on the "More" view at the upper right of the menu bar, the current settings
for the provider are displayed.
The settings for user-defined SIP providers can be changed under "Internet
telephony/SIP provider". The parameters for a default SIP provider cannot be
changed. In this case, create a new SIP provider and make the desired changes.
Setting up/changing an SIP provider
On this page you can create SIP providers yourself. If you would like to communicate
via a SIP server in your local network, you also create an SIP provider. The number of
providers is limited to 20.
If you would like to save changes for a provider, press the "Apply" button. "Reset" will
restore the last settings that were changed as long as these have not yet been
transmitted to the device.
Note: A change to provider data is applied immediately to the SIP accounts
that use this provider. Depending on the change that has been made,
the device will automatically log off from the providers and will re-
register itself with the new settings. Voice connections in progress are
terminated.
SIP provider
Here you choose whether you would like to create a new provider data record or
change an existing user-created data record.
