Have you faced the problem where your WAP Push or OTA configuration message displays "Unknown Sender"? While this occurrence does not result in a loss of functionality, it does appear less that professional. (If you have yet to experience this, send a WAP push message to a SonyEricsson P900.)

NowSMS v5.51 now includes the ability to specify the initiator URI, which some phones will display as the sender of WAP push or OTA configuration messages.

Under the [SMSGW] section header of SMSGW.INI, the setting "WAPPushInitiatorURI=" can be used to set the "X-WAP-Initiator-URI:" header, and "WAPPushFlag=" can be used to the set the "Push-Flag:" header.

In most instances, you will want to set the WAPPushInitiatorURI value to a web URL, including the "http://" prefix, and if only a host name is specified in the URL, include a trialing backslash to avoid problems with some devices (e.g., use "http://support.nowsms.com/discus/").

The WAPPushFlag can generally be ommitted. When specified, values of 1, 2 or 3 are expected. According to the WAP Push protocol, a value of 1 indicates that the initiator URI has been authenticated by the Push Proxy Gateway. A value of 2 indicates that the content of the push is trusted by the Push Proxy Gateway. A value of 3 combines both of these settings.

"WAPPushInitiatorURI=" and "WAPPushFlag=" parameters can also be used in HTTP requests when submitting WAP Push or OMA OTA messages.
