If you make internet telephone calls without voice compression (in accordance with
standard G.711), you need a bandwidth of approx. 85 kbps per call. If you want to
use a standard ADSL connection with an upload rate of 128 kbps, this may lead to
problems with voice transfer if you use the internet at the same time
(upload/download of files). In this case, make sure your router gives priority to voice
packets. Contact your router manufacturer for information on this.
For technical reasons, voice quality over the internet depends on numerous factors
(bandwidth, router, network load). For this reason, Tiptel cannot accept liability for
terminated calls or malfunctions. Please contact your internet telephony provider.
