Create a set of account resources:
https://docs.2600hz.com/dev/applications/crossbar/doc/resources/
Then point no_match callflow at the account resources. Something like
{
"data": {
"numbers": [
"no_match"
],
"flow": {
"data": {
"hunt_account_id": "b20cc94c158666e83c546c0d75103f19"
},
"module": "resources",
"children": {}
},
Apologies for brevity.
