Coders
From the Coders screen you can configure the first to fifth preferred coders (and their
attributes) for the gateway. The first coder is the highest priority coder and is used by the
gateway whenever possible. If the far end gateway cannot use the coder assigned as the
first coder, the gateway attempts to use the next coder and so forth.

Description
Enable Proxy Hot-Swap redundancy mode.
No [0] = Disabled (default).
Yes [1] = Enabled.
If Hot Swap is enabled, SIP INVITE message is first sent to the primary
Proxy server. If there is no response from the primary Proxy server for
Number of RTX before Hot-Swap retransmissions, the INVITE message is
resent to the redundant Proxy server.
Number of retransmitted INVITE messages before call is routed (hot
swapped) to another Proxy.
The valid range is 1 to 30. The default value is 3.
This parameter is also used for alternative routing using the Tel to
IP Routing table. If a domain name in the routing table is resolved
into 2 IP addresses, and if there is no response for
ProxyHotSwapRtx retransmissions to the INVITE message that is
sent to the first IP address, the gateway immediately initiates a
call to the second IP address.
Username used for Registration and for Basic/Digest authentication
process with Proxy / Registrar.
Parameter does not have a default value (empty string).
Applicable only if single gateway registration is used
(Authentication Mode = Authentication Per gateway).
Password used for Basic/Digest authentication process with Proxy /
Registrar. Single password is used for all gateway ports.
The default is Default_Passwd.
The Authentication table can be used instead.
String used by the server and client to provide mutual authentication. (Free
format that is, Cnonce = 0a4f113b).
Default_Cnonce
The default is
Per Endpoint [0] = Registration & Authentication separately for each
endpoint (default).
Per gateway [1] = Single Registration & Authentication for the gateway.
Per Ch. Select Mode [2] = N/A.
Usually Authentication on a per endpoint basis is used for FXS gateways,
in which each endpoint registers (and authenticates) separately with its
own username and password.
Single Registration and Authentication (Authentication Mode=1) is usually
defined for FXO gateways.
