SIP protocol reply code
Respon code
The respon code contains and extends the HTTP/1.1 respon code. Not all HTTP/1.1 respon c
odes are properly applied, but only in the fold is appropriate. Other HTTP/1.1 reply codes should not be ud. And, SIP also defines a new respon code family, 6xx.
1 temporary respon 1XX
The temporary respon, that is, the message nature of the respon, indicates that the rver is processing the request, and has not decided the final respon. If the rver processing request takes more than 200ms to produce an end respon, it should nd a 1XX respon.
Note that the 1XX respon is not reliably transmitted. They don't cau the client to nd a ACK respon. A temporary nature (1XX) respon can contain a message body, including a ssion description.
