[Freeswitch-users] SIP phones -

Hi there again folks,
 for clarification, I don't know about the "pure SIP" versions or Poly deskphones
-- I whinged only about the Lync variants of their DECT phones.
In my case, once you've had one of your users blame you for the setup and describe the
Polycom kirk butterfly as looking like a sanitary towel (only less useful), it's hard
to retain your enthusiasm.

Do their pure SIP phones really need a separate boot server to be set up before they'll
work properly? For central config sure, but for general operation of individual phones?

Re. SIP Deskphones, the Aastras seem to be popular on site and work quite well.
We have a couple of hundred of them, and with no failures (at all) yet, so they must be
pretty robust.

Older Cisco desk phones have left me with mental scars -- don't know about the new ones.
[In the early days, Cisco's interpretation of SIP was kinda different, causing many debug
sessions to find out what they needed]
Grandstream 2K series worked, but suffered from unacceptable mains hum and odd little
incompatibilities with fS.
The Siemens/Gigaset SIP desk phones were pretty boring, IIRC, but had pretty good sound
 quality.
For the others, can't say.

all the best,
  Lawrence
