I’ve done a bit of searching on this topic, but so far turned up little in the way of useful info (“they all suck” not being useful). Hopefully this hasn’t been talked to death already!
Until recently, all the Asterisk-based systems I’ve built have involved SIP hard-phones (i.e., Polycoms, Ciscos) or analog phones. But several weeks ago I ended up needing some cordless SIP phones. Cost was the main factor involved - so after considerable reading I decided to grab a few Cisco 7920’s and install chan_skinny. There was already a WiFi network on site, and by all accounts the phones were enterprise-grade and fairly mature, so that seemed like the easiest way to go. I tested them for a few days around my office, and they seemed to work fine for what limited use I could put them through.
Fast forward to today - after a few weeks with the 7920’s, the users’ murderous tendencies are becoming increasingly difficult to control. They complain that the ringer isn’t loud enough, wish for longer battery life, and generally despise the flakiness associated with their running on Skinny instead of SIP like everything else (seems Asterisk has to be restarted once or twice a day to keep the phones behaving).
So now I’m shopping again. Because this is being done on the cheap, I don’t expect perfection - but I do need to make the users a little happier. I’ve been on the prowl for something inexpensive (as in under $100 each, need 4) that would be reliable enough for daily service. As cost is a big consideration, used units would be A-OK.
What phones have you had success with? Which ones do you avoid? I’m looking at the UTStarcom F1000 right now, but I’m not quite sold on it.
