set global callRouting routingLabel LYNCIOT_RL routingLabelRoute 1 trunkGroup LYNCIOT_TG ipPeer LYNCIOT_IPP inService inService
commit

3.11 Routing

Routing must be put in place to send calls to the correct destination. This scenario uses trunk group routing, but additional routing options can be used.

The configuration of both standard and username routes ensures that no matter which way the called party is addressed (a number or username) the SBC routes the message to the Core.

For the standard trunk group routing, create route entries that have matching criteria and a Routing Label destination.

set global callRouting route none Sonus_NULL Sonus_NULL username Sonus_NULL Sonus_NULL all all ALL none ERT.COM routingLabel LYNCERT_RL
set global callRouting route none Sonus_NULL Sonus_NULL username Sonus_NULL Sonus_NULL all all ALL none iot.com routingLabel LYNCIOT_RL
