Description
Used to select the Diffserv priority of signaling packets when DiffServ is the
is the selected method for packet priority encoding.
For any given DSCP level, the flag must be set to the full 8-bit hexadecimal
value of the DS/TOS byte, which contains the DSCP level as its upper six
bits.
For example, assuming that a DSCP level of 34 decimal is required: the
binary representation of 34 is 0b100010, which, when placed into the upper
six bits of the DS/TOS byte, becomes 0b[100010]00, or 0b1000 1000 =
0x88 hex. Thus the flag value should be set equal to 0x88.
Default: 0xA0
For use in Microsoft environments.
When set to YES, sends a new request on the same TCP connection
instead of opening a new connection.
Range: YES/NO
Default: NO
For use in Microsoft environments.
Session timer interval in seconds.
Default = YES
Determines the timeout characteristics of SIP TCP TLS connections.
Format: SIP_TCP_TLS_TIMERS = <string>
The string contains the following parameters:
Ct - Timeout of TCP CONNECT operation (seconds)
Cs - Timeout of TLS CONNECT operation (seconds)
A - Timeout of accept operation (seconds)
D - Timeout of disconnect operation (nanoseconds)
H - Timeout of handshake operation (seconds)
Default: <1,5, 4,500000,5>
SIP Timer type timeout settings according to standard or proprietary
protocol.
Possible values are:
0 - Default
1 - SIP Standard recommendation.
Note: For homologation and certification testing, this flag must be set to 1.
For use in Microsoft environments.
In case of forking, a tag conflict will be resolved when Status 200 OK is
received from an answering UA.
Default: YES
