route.dest.5

Default Value:
Valid Values: <Destination> <Netmask> <Transport> <Metric>
Changes Take Effect: At start/restart

This is an entry in routing table.
Format: sip.route.dest.x=[Destination] [Netmask] [Transport] [Metric]
To select an entry in routing table, we mask the outgoing IP Address with [Netmask]; if the result matches with the [Destination], we will accept that route. The [Transport] part determines the transport to use and maps to the index 'x' in one of the transports defined as sip.transport.x. In most of the cases, first accepted route will be used. Unless the protocol is specified or required (for example, when the message size is larger than mtusize, tcp is required to be used), the accepted route in routing table is also required to have matched protocol. If there.s no such route, default transport of that protocol will be used.
If all cases failed, sip.transport.0.s protocol will be obtained. The default transport of the obtained protocol will be used.
Note that [Metric] entry is needed but not used at this point.
For example: sip.route.dest.0=138.120.72.0 255.255.255.0 1 0
When we make a call to the machine 138.120.72.20, outgoing IP is masked with [netmask] using .bitwise AND. operator. In this case: 138.120.72.20 & 255.255.255.0 gives 138.120.72.0. This matches the defined [Destination] in the route. Therefore, transport in sip.transport.1 will be used.
