SIP Server Domain Name Resolution
Description
Configures the time (in seconds) for the phone to
retry to send requests to the primary server after
failing over to the current working server for account
X.
If you set the parameter to 0, the IP phone will not
send requests to the primary server until a failover
event occurs with the current working server. If you
set the parameter from 1 to 59, the timeout will be
60 seconds.
Note: It works only if the value of the parameter
“account.X.sip_server.Y.failback_mode” is set to 3
(duration).
Default Value
3600
Range 0, Integer from 60 to 65535
Example account.X.sip_server.Y.failback_timeout = 3600
Parameter
-
account.X.sip_server.Y.transport_type
(X ranges from 1 to 16, Y ranges from 1 to
2)
Configuration File
<MAC>.cfg
Description
Configures the transport method the IP phone uses
to communicate with the SIP server for account X.
0-UDP
1-TCP
2-TLS
3-DNS-NAPTR
If the value of this parameter is set to 3 (DNS-
NAPTR), the value of the parameter
“account.X.sip_server.Y.address” is set to a host
name and the value of the parameter
“account.X.sip_server.Y.port” is set to 0, the IP
phone will perform the DNS NAPTR and SRV
queries for the transport protocol, ports and
servers.
If the value of this parameter is set to 3 (DNS-
NAPTR), the value of the parameter
“account.X.sip_server.Y.address” is set to an IP
address and the value of the parameter
“account.X.sip_server.Y.port” is set to an explicit
port (except 0), then UDP is used.
