VoIP Outbound Call Routing

Calls made from Line 1 are routed through the configured Line 1 service provider, by default. You can
override this behavior by IP dialing, through which the calls can be routed to any IP address entered by
the user. SPA3102 allows flexible call routing with four sets of gateway parameters and configurable
dial plans.

Group Description
PSTN
Line
PSTN If yes, SPA3102 detects prolonged silence period as
Line a disconnect signal. Default = Yes
PSTN The minimum duration of continuous silence before
Line the SPA3102 disconnects the call, if <Detect Long
Silence> is enabled. Default = 30 (s)
PSTN Tone Script of the disconnect tone to detect. Default
Line = "480@-30,620@-30;4(.25/.25/1+2)". Note:
The SPA3102 supports two frequency components.
If the tone has only one frequency, use the same
value for both frequencies.
Each cadence segment must have the same
frequency.
The level value is the threshold to detect each tone.
The total duration is the minimum duration of the
tone to be recognized as the disconnect tone
PSTN If yes, SPA3102 interprets polarity reversal as a
Line disconnect signal.
On an inbound PSTN call, SPA3102 disconnects on
the first polarity reversal. On an outbound PSTN
call, SPA3102 disconnects on the second polarity
reversal (because the first polarity reversal indicates
the outbound call is connected). Default = Yes
PSTN If yes, SPA3102 interprets the disconnect tone as
Line specified in <Disconnect Tone> as the disconnect
signal. Default = Yes
PSTN This is the signal energy threshold. Below this
Line threshold is considered silence. Default = medium
Table 1-30 lists VoIP outbound call routing parameters.
If yes, SPA3102 detects CPC as a disconnect signal.
Default = Yes
