Thanks for your reply! We’ve actually decided on this phone here:
What do you think about that model? Also regarding the echo cancellation, do you have a recommendation on something that does this driven through hardware as you suggested? This phone system will be used by a business so you could consider it mission critical that it work correctly.[/quote]
If you ask 10 people about hardware you will probably get 10 opinions.
Here are my opinions:
People seem to like the Cisco’s but hate the price and configurability. Everything from Cisco is overpriced IMHO. There is always that “agenda” of Cisco’s to “encourage” an all Cisco solution. Couple that with licensing fees to pay for firmware upgrades to fix problems you should not have to pay for, lack of factory support for Asterisk, difficulty of configuration. Cisco is a non-starter for me. More hassle than I am willing to deal with while paying a premium price. Nobody is going to get fired for going with a Cisco phone though.
If you can afford Cisco phones you can surely afford an extra $300 for a hardware echo can so get a Sangoma A200D (The “D” means it included the echo can module)and your guaranteed to have excellent sound quality, no echo, and no motherboard compatibility issues. Guaranteed!
Echo is by far the biggest potential issue you will face. I would sooner pay more for hardware echo can and cheaper phones than the other way around but ideally you should not try cut corners on either.
If course you need a solid platform to run it all on so that means commercial grade server hardware. Not those cheap Dell servers either. Some guys even try run this stuff on those el cheapo $299 Dell Dimensions (cringe!). Yikes!
