call, SPA disconnects on the 1
st
polarity reversal. If
it is an outbound PSTN call, SPA disconnects on
the 2
nd
polarity reversal (since the 1
st
polarity
reversal indicates the outbound call is connected).
Default = Yes
Detect Disconnect
Tone:
FXO
If yes, SPA will detect the disconnect tone as
specified in <Disconnect Tone> as the disconnect
signal. Default = Yes
Silence Threshold:
FXO
Signal energy threshold below which considered
as silence; one of {very low, low, medium, high,
very high}. Default = medium

VoIP Outbound Call Routing
Calls made from Line 1 are routed through the configured Line 1 service provider by default. This
behavior can be overridden by IP dialing where the calls can be routed to any IP address entered by
the user. SPA-3000 allows more flexible call routing with the addition of 4 sets of gateway
parameters and new dial plan syntax:
Parameters
Group
Description
Range
Gateway 1
Line 1
FQDN of a gateway. It can be a hostname or IP
address, with without a port number. If port
number is not specified, 5060 is assumed.
Default value is [blank]
FQDN
GW1 Nat
Mapping Enable
Line 1
Whether to enable NAT mapping when using
Gateway 1. Default is “no”.
BOOL
GW1 User ID
Line 1
The authentication user name when using
Gateway 1. Default is [blank]
Str31
GW2 Password
Line 1
The authentication password when using
Gateway 1. Default is [blank]
Str31
Similar for GW 2, 3,
and 4
Line 1
Similar for GW 2, 3, and 4
Gateways 1 to 4 can be specified in a dial plan with the special identifier “gw1”, … “gw4”. Also we use
“gw0” to represents the internal PSTN gateway via the FXO port. One can specify in the dial plan to
use gw
x
(
x
= 0,1,2,3,4) when making certain calls. In general, one can specify any gateway address
in the dial plan. In addition, we added 3 parameters that can be used with call routing: “usr”, “pwd”,
and “nat” which are, respectively, the user-id and password to be used for authentication with the
given gateway, and whether to enable NAT mapping when calling that gateway. Below are some
examples
Example
Description
<9,:>xx.<:@gw1
Dial 9 to start outside dial tone, followed by 1 or more digits,
and route the call to Gateway 1.
[93]11<:@gw0>
Route 911 and 311 calls to the local PSTN gateway
<8,:1408>xxxxxxx<:@pstn.sipura.com:5
061;usr=joe;pwd=joe_pwd;nat>
Dial 8 to start outside dial tone, pre-pend 1408 followed by 7
digits, and route the call to pstn.sipura.com:5061, with user-id
= joe, and pwd = bell_pwd, and enable NAT mapping
<8,:1408>xxxxxxx<:@gw2:5061;usr=”Al
ex Bell”;pwd=”anything”;nat=no>
Dial 8 to start outside dial tone, pre-pend 1408 followed by 7
digits, and route the call to Gateway 2, but use the given port,
user-id, and password, and no pstn.sipura.com:5061, and
