Additional settings for Internet telephony can be configured on the "Advanced Settings" page.
Internet phone connections can only be established when the party's complete number is entered, including the country and area code.
Enter your country and area code in the location information so that you can continue to make local calls without having to add this information to local numbers. The FRITZ!Box will then add the required prefixes automatically.
When this setting is enabled, pauses in speech during an Internet call are detected. No data are transmitted during this time. This thus reduces saves online charges by reducing the amount of data transmitted.
Note: Enabling VAD can result in impaired voice quality on the remote site.
The voice compression preset in FRITZ!Box automatically adapts to the available bandwidth and the number of calls being conducted at the given time. You can also configure static voice compression.
With this setting you can assign values to the IP packets used for voice transmission. The values are written to the relevant IP packets so that they can be distinguished from other IP packets. Marking the voice packets in this way makes it possible for routers that support this indication to handle voice data preferentially.
With an additional connection for Internet telephony over DSL, the telephony data can be transmitted separately from the data coming from the computer. Instead, the FRITZ!Box establishes another ATM connection using the same ADSL line.
This function must be supported by both your ADSL provider and your Internet telephony carrier. Contact your ADSL provider to find out which settings are required for this function.
Enable this option if your Internet telephony provider uses the T.38 standard.
