FAQs 

?

 

Does the innkeeper LTD send a burst or beep down the phone 
line at the beginning of each call like our  current hybrid? 

 

!

 

No, innkeeper LTD uses the actual transmit signal to evaluate the 
phone line and tune its algorithm. As you begin to speak, innkeeper 
LTD is hard at work canceling your voice from the Caller Output jack. 
Within milliseconds your voice is reduced into the noise floor.

Can I use the innkeeper LTD on a VoIP line?

 

!

 

Many VoIP lines have an analog telephone adapter you can connect 
your telephone to. If you can use any standard analog telephone, 
then innkeeper LTD should work great. If you have to use a specific 
telephone, you should consider our PBXport digital hybrid instead.

The caller’s audio is too high and is always distorted even 
though I have the Caller level control turned down low. What 
else can I do?

 

!

 

The Receive LED meter will indicate the level of audio coming in from 
the telephone line, just after it passes through the DSP. The Caller 
level control will only set how much of that audio will be sent to the 
output jack, and will have no effect on the LED meter. If your incom-
ing audio level is unusually hot and already peaking the –3 dB LED, 
there is a jumper on the circuit board you can change to attenuate 
the incoming audio. Please see page 13 for more information.

I have my new innkeeper LTD connected to the phone jack in 
my office. Why does it keep dropping the calls as soon as I try 
to connect it?

 

!

 

The telephone jack in your office is very likely for a multi-line phone 
system. The jack may look like a standard phone jack, but it is wired 
differently and may carry voltage on different pins which could cause 
serious damage to your hybrid. Innkeeper LTD should only be con-
nected to a single, analog phone line. Check with the telephone spe-
cialist in your building for the possibility of getting an analog line for 
your innkeeper LTD.

 

 

?

 

My innkeeper LTD is connected to an analog line at my office 
location, and will auto-answer an incoming call.  Why won’t it 
auto-disconnect at the end of the call?

 

!

 

A PBX phone system can be programmed to provide an analog 
line. Check with the telephone specialist in your building for the 
possibility of resetting the characteristics of your analog line to pro-
vide an appropriate CPC disconnect signal.
