I'm quoting out a 3CX system for a potential client. What phones should I quote him? It's a small office, 5 phones total. Here's what I'm putting in for options, all have 2 RJ45 so no new wiring needs to be done: Linksys SPA-942 - $145 retail Grandstream GXP-2000 - $80 retail Grandstream GS-102 - $50 retail Is there anything else I should look at or is there better equipment in the same price range? Also has anyone tried the Linksys WIP300 wireless phone? Thanks!
