Automatically reply to INVITE with "100 Trying" response
Whether to automatically reply to INVITE requests with a 100 Trying response. Disabling this setting might increase the number of INVITE retransmissions.
Data type Boolean Default True
Hide message body
Whether to hide message content in log files. Set the value to True to remove the message body text from SIP messages printed in the log files. This setting only affects the representation of the messages in log files.
Data type Boolean Default False
Enable outbound connection timeout
Whether to enable the outbound connection timeout.
Data type Boolean Default False
Outbound connection timeout
Amount of time, in milliseconds, for creating outbound connections. This setting is relevant only for stream transports, such as Transmission Control Protocol (TCP) and Transport Layer Security (TLS). The default value of 0 provides an infinite amount of time.
Data type Integer Default 0
Maximum transmission unit
Maximum transmission unit, in bytes, for outbound User Datagram Protocol (UDP) requests. The SIP stack measures the size of a request before sending it out on the UDP channel. If the request is higher than the value specified for PATH_MTU-200, 1300 bytes by default, then the transport is switched from UDP to TCP before transmission.
Increase this value to send larger requests over the UDP channel; however, messages might be truncated or discarded. See the RFC 3261-18.1.1 specification for details.
Data type Integer Default 1500
Outbound proxy
Fixed address for routing all outbound SIP messages. The format is address:port/transport, such as 1.2.3.4:5065/tcp.
Best Practice: Do not use this setting if the container is fronted by an application server SIP proxy.
Data type String Default empty string
Configure the SIP container
