Configuring SIP extensions

Strict SIP routing
Strict SIP routing is supported. In a complicated network environment where a request from SIP UAC
to SIP UAS needs to pass through multiple proxy servers, SIP uses the Route header field and the
Record-Route header field to make sure that requests in the dialog can be routed through these
proxy servers. The strict SIP routing is enabled by default, and you do not need to configure it.
Configuring out-of-band SIP DTMF transmission mode
During the communication between caller and callee, the DTMF digits can be transmitted
transparently between them in two ways: in-band and out-of-band. In the in-band approach, the
DTMF digits are encoded in RTP voice packets, and in the out-of-band approach, in SIP messages.
