Call Forwarding

Call Forwarding and Callee ID

My recommendation would be to not forward the calls to Twilio and call the Twilio number directly. The ability to capture the original called number is carrier dependent and not reliable.

You could also forward the call to Twilio via SIP (rather then over the Public Switched Telephone Network), and possibly pass an X-Header with the original Caller ID, but that is most likely not possible with your existing carrier.

Android : Set Call forwarding after a delay

UUID Code 21 Diverts all Calls

So to Divert if no Reply we have to Use
UUID Code 61

So Replace :

String fwdMobNumVar = ("**21*" + mobNumVar + "#");

with

=> For 5 Sec Delay :

String fwdMobNumVar = ("**61*" + mobNumVar + "*" + 5 + "#");

=> For 10 Sec Delay :

String fwdMobNumVar = ("**61*" + mobNumVar + "*" + 10 + "#");

How can I speed up call forwarding on Twilio? - Django

Twilio developer evangelist here.

It appears that you are both reading data from and then saving data to a database before you respond with the TwiML to tell Twilio to forward the call. To get the quickest forwarding you should return TwiML as quick as you can.

Perhaps you can test the same forwarding without hitting the database and see if there is a difference. If there is, then I can see you need to read the database to get the number to forward to, but perhaps you could set up the saving of a new Lead to be done in a background job rather than block the response with it.

Another thing to try is to set answerOnBridge="true" on your .

Let me know if that helps at all.
