I was doing some testing with my phone tonight regarding conference, three-way and 4way calls. I was not really pleased with the results: 1. You cannot merge an incoming call with an existing call 2. You can do 3 way calling but when you try to add a 4th call it drops one of the other calls 3. When you are on a 2 way call incoming calls go directly to voicemail. 4. When you have 1 call on hold or are on a 3 way call if you press end call it disconnects both and one of the calls will ring back in. I have an iPhone for work and am able to do all the above very easily. I was wondering if these are limitation on Verizon's network or with Android's call management system.
