About Branch Bnumber#

Try to branch to the capture group of the feature code

Schema#

Validator for the branch_bnumber callflow data object

Key	Description	Type	Default	Required
`hunt`	Should the capture group be used to hunt for a new callflow	`boolean()`	`false`	`false`
`hunt_allow`	A regexp used to match against the capture group to whitelist allowed numbers to hunt	`string()`		`false`
`hunt_deny`	A regexp used to match against the capture group to blacklist denied numbers to hunt	`string()`		`false`
`skip_module`	When set to true this callflow action is skipped, advancing to the wildcard branch (if any)	`boolean()`		`false`

Branching vs Hunting#

Branching#

With the hunt flag set to false, the capture group will be used to lookup a child branch that matches:

{"patterns":["*55(\\d+)"]
 ,"flow":{
   "module":"branch_bnumber"
   ,"data":{}
   ,"children":{
     "_": {...default branch...}
    ,"{CAPTURE_GROUP}": {...exact match on capture group...}
   }
 }
}

So if the caller dials *551000 a child key 1000 would need to exist and define the rest of the callflow.

Hunting#

This isn't particularly useful if you want a more dynamic experience. By setting hunt to true, the capture group can point to another callflow and branch to its flow. This could be used to create specific flows based on feature code that branch to the "normal" flow for the capture group.

For example, enabling per-call call recording could be implemented as:

{"patterns":["*55(\\d+)"]
 ,"flow":{
   "module":"record_call"
   ,"data":{...}
   ,"children":{
     "_":{
        "module":"branch_bnumber"
        ,"data":{"hunt":true}
     }
   }
 }
}

Now, when *551000 is dialed, call recording is started and then a hunt for 1000 is performed as if the caller had just dialed that to start. If found, the normal callflow for 1000 runs, just with call recording enabled.
