Ask HN: What phone systems do you use for your business?

- Consumer-style services like Google Voice or Skype?

- Small business hardware solutions like Avaya Partner ACS?

- Enterprisey hardware/software combos like Cisco CallManager?

- Hosted VOIP vs. in-house hardware?

What are your likes, dislikes, pros, cons, etc.?

What would you recommend to a company of about 10-15 employees that has low call volume (about 60-70 calls/day).

Thanks for any suggestions and ideas.
