Hello,

We're trying to test WAP Push provisioning over-the-air (OTA) via SMS by
using two Windows Mobile devices - one as a sender, the other as a receiver.

When the receiving device receives the provisioning message (the message
just adds a new browser Favorite, and the message is unsigned), the
following "Confirmation" prompt appears:

"From unidentified sender: This changes device settings.
Caution: unauthenticated message.
Accept?"

When hitting 'Yes', the Browser Favourite is created properly.

Question 1: what does 'unidentified sender' mean? When sending a regular
text SMS message, the receiving phone can decipher the sender's phone
number, e.g. +61410022305. When receiving a WAP Push message, shouldn't the
receiver know the message comes from a particular phone number? Or does
'unidentified sender' means something else.

To send the provisioning message, we're using a modified version of the
WDP_SMS sample code to send the message (the original code can be found in
the 'Windows CE' SDK, e.g. in 'C:\Program Files\Windows CE
Tools\wce500\Windows Mobile 5.0 Smartphone
SDK\Samples\CPP\Win32\Cellcore\Wdp_sms') from the sending Windows Mobile
device. Now, we've set up the WAP_ADDRESS's for the sender's number, and the
receiver's number.

Question 2: At present, the receiving device can only receive the
provisioning message when the device is completely unlocked (we used
'unlock.xml' as attached here). We're trying to set up a Trusted
Provisioning Server (TPS) and a Push Proxy Gateway (PPG) for the receiving
device to accept messages from the sending device, as identified by a phone
number. We tried doing this via 'WapTrustedGateway.xml' (as attached).
However, the receiving device simply drops the incoming message without any
prompt or messages. How do we set up the receiving device to only accept
unsigned messages coming from the sending device by recognising the sender's
phone number?

Your help would be much appreciated. Thanks!

Regards,

Isaac
