Defines the server provisional response (101-199) retransmit timer in milliseconds.
The timer starts after a 101-199 provisional response is sent for the server INVITE. If a final
response is not ready before the timer expires, the UA transaction will retransmit the provisional
response to extend the transaction on the proxies (refresh TIMER C).
Note that the [sip]timer.provretransmit value should be configured to 150000 ms if reliable provisional
responses is enabled (please see the description of the [sip]prack.support parameter ).
If the value of the parameter is set outside the defined range, the actual value will use the boundary value.
The default value is 60000.
