Kudos to VOIP Supply’s Garrett Smith for plainly explaining the truth about wifi SIP devices, and specifically why Vonage stopped offering them. You can’t put it any more plainly than, “They suck.” The really curious part is that VOIP Supply probably sells more Wifi SIP phones than anyone else.
Others I’ve spoken within the industry have echo’d this feeling about SIP Wifi devices, although not so openly. My own experience with the Hitachi Cable WIP5000 (shown right) bears this out as well.
It is interesting that the one exception to this rule is the Vocera VOIP badge, which I encountered deployed at a major local hospital. Speaking with their staff it appears that they love the little device. But it’s not exactly a run-of-the-mill Wifi phone.
In contrast, thus far my experience with the Snom M3 SIP/DECT phones has been very good. I also hope to eventually get access to some of the new Polycom Spectralink & Kirk product for trial later this spring.
