provide RTP packets with a busy tone or the SIP 486 Busy

the system.

Pre Audio
Connection For
DTMF
The system normally provides the 183 Session Progress SIP
message to establish a “Pre-audio” connection.
The “Pre-audio” connection permits the system to send tones (CO
dial tone or ringback tone) to the SIP phone.
In addition, the SIP phone can send DTMF tones the user dials in
response to CO dial tone or a remote IVR message.
Some SIP phones may require the 200 OK messages, which
“answer” the call, to allow dialing after the call has been initiated.
