Unfortunately, this particular hardware does not provide FXO signaling.
Incoming calls work perfect, the phone rings and voice flows on both
directions. However, I can't place outgoing calls, there is no dial tone
and dialing out makes no difference.
Does anyone know how to configure asterisk to emulate FXO signaling or
point me in the right direction ?
What hardware is it, exactly?
It is a small SOHO router from LinkSys that has 2 FXS ports, an ethernet
switch with 4 ports and a wireless interface. It came with Linux 2.6.14
installed and a VOIP application which uses 40% CPU when a call is up.
I'm trying to replace this VOIP application with asterisk configured as
TA (basically asterisk is a VOIP phone). I think the phone hardware is
based on legarity slics.
Did you actually get Asterisk running on it?
Are there free drivers for the wireless innterface (so you won't depend
on the specific kernel version)?
You can't simply use the existing zaptel drivers, as the adapters don't
even sit on a PCI bus. If the slics are indeed the same ProSlics used by
the TDM400P, it could help. But some driver rewriting would probably be
needed.
Are there any existing free drivers that use those adapters?
Yes, I got asterisk to come up. I can receive calls with no problems. It
is outgoing calls that doesn't work. I think the VOIP application that
came with the router generates the dial tone and detects dtmf digits. It
looks like asterisk is not doing that. I'm going through the asterisk
code to see if I can find out how to enable dial tone generation and
dtmf digit detection.
