The hype over internet telephony software such as Skype is doing little to benefit sales of equipment designed to work with such programs, hardware manufacturers in Taiwan say.
Though Skype has achieved more than 100 million downloads, sales of gear created to work with the program have done poorly - primarily because the equipment is annoying to configure.
True, sales are growing, but this is off a low base as the sector is just getting started.
'I don't think [VoIP] is a really big trend,' said Murray Huang, a spokesman at C-Media, which makes audio controller chips for VoIP phones.
One problem is that in order for one IP device to talk to another, it needs to know where and how to find it.
It is very easy to make a VoIP call if you know the IP address of the recipient's phone - it is a static address that never changes. But this is assuming the recipient has a VoIP phone in the first place, and that it is plugged in, turned on and not behind a firewall or router.
