Audio Configuration section
A codec resource is considered as allocated if it has been included in the SDP
codec list of an active call, even though it eventually may not be the one chosen for
the connection. So, if the G.729a codec is enabled and included in the codec list,
that resource is tied up until the end of the call whether or not the call actually uses
G.729a. If the G.729a resource is already allocated and since only one G.729a
resource is allowed per device, no other low-bit-rate codec may be allocated for
subsequent calls; the only choices are G711a and G711u. On the other hand, two
G.723.1/G.726 resources are available per device.
Therefore it is important to disable the use of G.729a in order to guarantee the
support of two simultaneous G.723/G.726 codec.

Gateway Accounts section (SPA3102)
Gateway1/2/3/4
The first of 4 gateways that can be specified to be used in
the <Dial Plan> to facilitate call routing specification (that
overrides the given proxy information). This gateway is
represented by gw1 in the <Dial Plan>. For example, the
rule 1408xxxxxxx<:@gw1> can be added to the dial plan
such that when the user dials 1408+7digits, the call will be
routed to Gateway 1. Without the <:@gw1> syntax, all calls
are routed to the given proxy by default (except IP dialing).
The default is blank.
GW1/2/3/4 NAT
Mapping Enable
If enabled, the ATA device uses NAT mapping when
contacting Gateway 1.
The default is no.
GW1/2/3/4 Auth ID
This value is the authentication user-id to be used by the
SPA to authenticate itself to Gateway 1.
The default is blank.
GW1/2/3/4
Password
This value is the password to be used by the SPA to
authenticate itself to Gateway 1.
The default is blank.
