SIP Phones

Which phones to standardize on?
- Snom
- Skinny
- Polycom
  - I like Polycoms. For your use case, an IP 33X would work well. We have IP 335's but any in that category would do.
  - I HATE Polycoms they are hard to configure and hard to debug.
  - IMHO these don't even reach the 'blows goats' level. Work has 50 of them; user feedback is that voice quality, coverage, battery life is "not as good as we might hope".
  - Boot server seems best way to config
  - VVX 300/310 are low cost new models.
- Siemens- Gigaset ( DECT )
  - 610IP is a great cordless ip-phone. Works perfectly with FreeSWITCH. You can also have several handsets served from one base.
  - SIP desk phones were pretty boring, IIRC, but had pretty good sound quality.
- Cisco
  - my favourites are Cisco SPA50x series both blind and attended transfer buttons and BLF
  - Older Cisco desk phones have left me with mental scars

- Yealink
- Aastra
- Grandstream
  - Grandstream 2K series worked, but suffered from unacceptable mains hum and odd little

incompatibilities with fS.

Many use PoE(Power over Ethernet) - and there is at least 2 standards..

POE can be IEEE 802.3af (about 13W) or IEEE 802.3at(about 25W) -- some out of standard claim 50W..

Looks like most SIP phones only need the af - most use about 2-3W ( probably less these days.. )

POE giga-bit switches are not commodity cheap yet..
