Hi, I'm new and very interested by 3CX. But, I generally found a 3CX usage for around 10 to 30 users, with up from 0 to 5 remote sites. In my case, I got 150 users, 15 remote sites, and about 500 calls a day. Main site will host data servers and phone server (3CX???) with 8M SDSL + QoS. Remote sites will be configured with 2M SDSL + QoS, with a maximum of 5 users per site. I'll be glad to share some similar experiences with you guys. That will make me more confident. Theorically, 3CX rocks... But in real life, will it be efficient and reliable enough to match my needs ????? Thx very much by advance.
