Description
When using an unreliable transmission protocol such
as UDP, retransmission is required when no reply is
received. RE-TRANS.T1 TIME is the initial retrans-
mission interval defined in RFC2543.
Maximum retransmission interval defined in RFC
2543
RFC 2543 defines this parameter for various pur-
poses. For example, this parameter can be used as
the time waited by User Agent Server after receiving
ACK message in an unreliable transmission proto-
col.
When using an unreliable transmission protocol, the
server cannot be sure if the client has received the
last reply. Thus, the server must retransmit the reply
for this length of time until it receives the requested
retransmission. For example, this parameter can be
used as the waiting time after sending 200 OK for
INFO.
When using an unreliable transmission protocol, the
client cannot verify if the server has received the
ACK returned to the server for the INVITE Final Re-
sponse. The client waits for this length of time after
sending the ACK for the Final Response.
Waiting time before cancelling SIP related Request.
Waiting time before cancelling SIP INVITE Request.
Waiting time for receiving final response for SIP re-
lated Request.
On receiving Provision Response, the User Agent
must wait for this length of time until Timeout.
