.Automatically reply to INVITE with "100 Trying" response
Specifies whether to automatically reply to INVITE requests with a 100 Trying response. Disabling this setting might increase the number of INVITE retransmissions.

Hide message body

Outbound connection timeout
Specifies the 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.
Information | Value |
---|---|
Data type | Integer |
Default | 0 |
Maximum transmission unit
Specifies the 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.
Information | Value |
---|---|
Data type | Integer |
Default | 1500 |
