1. Meetme/Call Conferencing not working
|This happens when there
is no timing device installed on the server. Timing is
provided by the FXO, FXS or PRI hardware, like a Digium or a
Sangoma card. If there is no hardware installed, there much be
ztdummy module enabled during zaptel installation.
2. Call Waiting not working
|In my experience, Call
Waiting works perfectly fine. The only catch is that it is
disabled by default. After the installation of Trixbox, all
the phones attached to the system must be enabled for call
waiting by dialing *70#.
