Parameter

Description

fetch_after_attempt

Optional;
default = false

This parameter will indicate if, after each unsuccessful dial attempt within connect, the parameters should be fetched again including destination numbers.

`false` will indicate, dial attempt to happen based on the initial response. No subsequent hits to the URL.

`true` will indicate if connect parameters including a number to dial should be fetched again (hit the configured URL again) if the dial attempt is unsuccessful.

NOTE: If 2 subsequent fetch results contain exactly the same set of destination numbers, Exotel will not make any subsequent attempts even if fetch_after_attempt is set to true.

Request:
GET /<customer-url>

Apart from standard request params, it’ll include <connect> params from the previous dial attempts.

Response:
<Same as above>

destination

Mandatory

Indicates the destination(s) to dial out.

Sample:

“destination”: { 

  “numbers”: [“+622131921111”, “+622131921112”]

}

outgoing_phone_number

Optional;
default = Incoming ExoPhone

ExoPhone to be used for dialing out in E.164 format.

Validations:

• The ExoPhone added should be present in your account.

• Restrictions will depend on telecom regulations i.e. another call can only be dial-ed out from the same telecom circle/region. For example, outgoing ExoPhone cannot be set to Delhi where Incoming ExoPhone is in Bangalore.

• Both the first leg and the second leg ExoPhones can be connected on the same server.

NOTE: If ExoPhone is not present in your account or the ExoPhone is unable to dial out i.e. if the above validation fails, then the call would be dial-ed out using the same ExoPhone as the first leg (where the incoming call landed).

NOTE: Consult with exotel support to use this feature.
