Busy Detection is enabled.
Input Volume: The volume of the incoming calls from FXO channel/channels.
Output Volume: The volume of the outgoing calls from FXO channel/channels.
Call Progress: If enabled, call progress attempts to determine answer, busy, and ringing on
phone lines. This feature is HIGHLY EXPERIMENTAL and can easily detect false answers and
therefore can prove unreliable.
Progress Zone: Progress zone also affects the pattern used for busy detection, only effective
when Call Progress in turned on.
Busy Pattern: If busydetection is enabled, it is also possible to specify the cadence of your
busy signal.
Language: You can choose adesired language of the system voice prompts to play to the
incoming calls from this trunk. For example, if the call is not answered or the user is busy the
IPPBX system will notify the caller to leave a voice message in the language you set.
Answer on Polarity
Switch: When enabled, FXO (FXS signaled) ports watch for a polarity
reversal to mark when an outgoing call is answered by the remote party.
Hangup on Polarity
Switch: In certain countries, a polarity reversal is used to signal the
disconnection of a phone line. If the "hanguponpolarityswitch" option is selected, the call
will be considered "hung up" on a polarity reversal.
When creating a FXO trunk, if you are not competent with the advanced options then please do
not configure or change the default values.
3.2 Outbound Routes
Outbound Routes allow you to define a set of dial rules that tell yourCooVox IPPBX which Trunks
(phone lines) to use when people dial external telephone numbers. A simple installation will
direct CooVox IPPBX to send all calls to a single trunk. However, a complex setup could have for
example an outbound route for emergency calls, another outbound route for local calls, another
for long distance calls, and perhaps even another for international calls.
With all of the above possibilities, you may have to configure several trunks onyourCooVox IPPBX
system and therefore you will need to configure several dial rules and maybe also several dial
plans.
