Tpad & Didww
 

Didww does not has direct mapping with Tpad, the work around to map DID is as following

1. Add URI
2. After add name
3. URI:Sip / *xxxxxxx@sip.tpad.com
4. Add

Note do not forget to add * before xxxxxxx tpad number.

Is this true?
 

Is this true?

As far as I know, you cannot call Tpad's SIP adresses from other networks. Inbound calls to a Tpad SIP adress are only possible if the caller is also a Tpad user. (Outbound calls from a Tpad adress are possible though.)

So your design shouldn't work.

What am I missing?

Curently I am using form Didww and with Voxalot using sipbroker in speed dial
use *8142*xxxxxxx

It works try.

Here is a guide on how to do:
