Cellular Phone Forum / Country Specific / Australian Group / May 2008Remote diversion change
Hi ALL, Does anyone know if it is possible (by SMS'ing a GSM code type arrangement) to change the diversion (forwarding) number on an unattended mobile telephone. Do I have to have an application on the phone to facilitate this? Any info/ideas would be great. Thank you. Mouse > Hi ALL, > [quoted text clipped - 3 lines] > on the phone to facilitate this? Any info/ideas would be > great. I seriously doubt it's possible, for security reasons alone. Another aspect is that the diversions are not held on the phone - they're part of your configuration data on the network itself. For that reason, you may have noticed that you can't change diversions when there's no coverage. Changing diversions using the phone's menu system attempts an immediate "supplementary services" data session with the network. So because networks have absolutely no requirement to modify diversion parameters on users handsets, I doubt that a specific GSM port number has been allocated to facilitate this. If it were possible, technical specification 3GPP 23.040 would provide the mechanism (section 9.2.3.24.3 or 9.2.3.24.4).

It involved dialling the Remote Control number on your home switch to get an interactive IVR, which stepped you through the process of changing Easycall settings on your home number remotely. Such a thing has never been done on the Telstra GSM network. You can however, call the Mobile helpdesk on 125111 and get them to set/change diversions for you if you can prove you own the service you want the diversions changed on. (for Telstra). Good luck. > Changing diversions using the phone's menu system attempts an > immediate "supplementary services" data session with the [quoted text clipped - 5 lines] > > John > Such a facility was available on Telstra's PSTN network, although > never used. What are you talking about? Everyone uses it >> Hi ALL, >> [quoted text clipped - 20 lines] > > John And after all that jibber-jabber, the answer is: THIS FACILITY DOES NOT EXIST IN AUSTRALIA > And after all that jibber-jabber, the answer is: THIS FACILITY > DOES NOT EXIST IN AUSTRALIA I'm sure that's right, at least for the combination of phone and network built-in features. But the more I think about it, the more I suspect that such an application /could/ be written for "smart" phones, like Symbians. And it could be secure too. Install a purpose-built application onto the phone, and ask the phone user to configure a password. Then the application would wait for a specially formatted SMS with password and diversion details. This would see the phone opening a supplementary services session (assuming support for that in Symbian), and changing the diversions. Maybe it's time I bought a Symbian phone and had a play with it.
