My question stems from a problem that we are having when switching from speaker to handset, and handset not picking up immediately. When on the speaker phone, and the handset is taken off-hook, the voice does not transfer, rather it continues to use the speaker. Sometimes when switching from handset to speaker, the phone hangs up. My question is this... Is the switch between the speaker phone and handset a function of the CCM, or is it a function of the phone itself? When I run a trace on a device that switches without problem, i see no difference between that and one that will not switch successfull. Additionally, I am seeing no lines in the trace that have anything to do with the switch. The trace looks exactly the same between all devices regardless of whther or not they work, seemingly indicatling that the switch is a function of the phone.
