There are funnels, but they have a different name, "Web Traffic Management", I should have chosen the words better
In other words, they have unlimited home internet up to 60mb / s, I talked to two of them and they both found that the internet calls even though they have normal internet after checking on the phone from another card to abo, i.e. "network traffic management" works
On this basis, they can block you, slow down or give priority to you, below is a quote from the regulations:
"The Operator uses traffic management measures in the Network,
whose aim is to support its effective
use and optimization of the overall quality of the service
telecommunications services provided with the use of
Network to all its subscribers, including broadcast services
data within the mobile and fixed Internet
(hereinafter "data transmission service"

. These measures prevent
reaching or exceeding the capacity
shared link and are necessary for proper
providing telecommunications services on the Web by
Operator to all its subscribers. Means
Network traffic management shall be non-discriminatory and
based on objective differences in requirements
regarding the technical quality of services in the field
specific categories of traffic. They do not
negatively on the privacy of end users, w
including the protection of their personal data. By means
traffic management is automatic: blocking,
slowing down and prioritization. Prioritization is about
on giving priority to certain categories
Web traffic, the quality of which is particularly at risk
or categories of traffic particularly sensitive to decline
quality. Traffic categories are e.g. voice calls,
mobile services, fixed-line services, broadcast service
data, video streaming (videostreaming),
data download. The result of prioritization
certain categories of traffic may be, inter alia, deterioration
quality of services / and in terms of traffic category not covered
priority (e.g. video streaming -
videostreamingu) - felt by users
end points temporarily, incidentally or periodically.
At the same time, however, thanks to the use of this measure
The operator will maintain the quality guaranteed by the contracts
another service that is used by the same or others
end users on its Network. Use
prioritization does not violate the provisions of the Agreement, incl
the level of Service quality guaranteed by it
Telecommunications, which also applies to services
not covered by priority. "
