Opera 4 IP System Manual
SIP SERVER: The location of the SIP server in the Operator's network. The Operator provides
this information. Typically it will be in the format sip.operator.com.
SIP SERVER PORT: This is the PORT number for the SIP protocol. By default it is 5060. If the
operator uses a different port number it should be entered here.
REGISTRATION REQUIRED: Is registration required by the network operator or not?
FORCED PROXY IP: The actual SIP server IP address must be entered here if it's different
from the IP address associated with the SIP server URL. The SIP operator may insist that all
SIP messages are relayed to the forced proxy IP address entered here; the SIP server URL is
included in the SIP messages from the system.
REGINTERVAL: The SIP protocol allows for periodic registration messages to be sent to the
SIP server in order to keep it updated it on the status of the SIP client. The parameter
RegInterval allows the system administrator to program the length of the registration interval in
seconds.
STUN SERVER: Some operators require the use of a STUN server (Simple Traversal of UDP
through NATS). If the operator provides the address of a STUN server with the account details,
it should be entered here.
Subscriber Settings
USERNAME: This is the username provided by the network operator for the SIP account.
PASSWORD: This is the password provided by the network operator for the SIP account.
AuthID: Authorisation ID, if required, is provided by the network operator.
EXTERNAL NUMBER: This is the public telephone number associated with this SIP account. It
is provided by the network operator and should be entered here. It is then added automatically
to the list of external telephone numbers of the system.
Audio Settings
Codec priority 1,2,3: These fields are used to set the preferred audio codecs.
DTMF Method: This parameter allows the system administrator to select the method of
transmitting DTMF digits across the VoIP network.
Dialling Settings
DIAL PLAN: During dialling on outgoing calls, the digits are stored until the complete number
has been dialled and then the complete number is transmitted en bloc to the VoIP network. A
period of three seconds without dialling is interpreted by the system as the end of dialling. This
means that the system must delay transmitting the number for a period of 3 seconds after the
end of the last digit. The Dial Plan allows the system administrator to define number types that
can be dialled immediately without waiting for the 3-second period to elapse.
