Hi,
I've set up a freepbx distro server with a combination of mitel 5212, 5312 and 5330 handsets. After reading a lot of articles on this forum, I've managed to get it working pretty well. (still some issues to resolve though)
I've come across a strange problem i can't find any documentation on. When a call is placed on hold for a longer period (>1 minute) the mitel 5330 handsets seems to block their blf keys at some point. So you have no way of getting the call back, and notify the caller. The caller gets MOH indefinitely. If you put the call on hold for a shorter period, everything works like it's supposed to and you get the call back by pressing the corresponding line key. If the phone blocks, the BLF lights are still working correctly.
Any Ideas?
