I like Polycom phones too but lately have taken a liking to Aastra phones
since they look/sound great, don't need any special PoE adaptors or
switches, and have very strong Asterisk support from their company. I've
tried various vendor hardware and the one I like the most is Xorcom's
hardware because it scales well, needs less hardware, has no issues
whatsoever with faxes (all their hardware locks via phase lock loop to a
single unit so everything has the same clock), uses USB so IRQ/DMA issues
aren't an issue ever like with some Asterisk hardware, and requires the
least amount of space. Xorcom USA like Rhino is right here in the valley so
you can get it tomorrow if you wanted.
I wire every office I can all cat6. They way I can change what a port is
without any hassle in he server room. Some things like credit card
machines, modems, or alarm circuits are finicky - wire them directly to a
phone line instead of going through asterisk. Don't use ATA's for faxing -
they work sometimes but if they don't it is a real headache. If you can
separate phones from the rest of their internet traffic do so. Many phones
have two network plugs (1 lan, one pc); I only use them IF I can't just
supply another network drop to a location.
