There is a trick, and the trick is known as QoS (Quality of Service).

QoS is a facility available on some routers and it provides a method
of giving your VoIP traffic higher priority than other connections so
as to reduce the delays to it which result in interruptions to the
voice signal. If you are doing a download at the same time as making a
voice call, the download will be throttled back as necessary to
maintain sufficient bandwidth for the voice traffic.

You might want to check out this list of routers which are reported to
support QoS.
