Yeah, that's what I already thought for myself. VoIP is (based on its realtime nature) extremely picky about network interfaces (or even complete hardware of the system) and their
drivers and the corresponding configuration. But most of the people can't / won't believe it.
Many of them (NICs) are pretty broken (sometimes the nic hardware, sometimes both hard- and software). Even APU 1 or 2 devices don't work reliably for VoIP with the standard in
kernel drivers or with default configuration here. I always had / have to use other drivers / kernels / configurations to get a proper and reliable rtp stream - even over hours.
