Dear all, First: I’m not a technically qualified person. I’m in business development and marketing. And co-founder of a small Dutch ICT company. (www.e-neo.nl) Second: This is my first contribution to the Maemo community. So I hope this request makes sense to you, the reader. Finally: This is a request for help to build a new Maemo application that would allow the N900 to become a softphone for the Avaya Communication Manager. The Avaya is a business communication platform. Previously known as PBX (private branche exchange). In the old world, it’s the server that operates those phones on desks that don’t go anywhere. The Maemo softphone for Avaya would do this: - SIP register as an extension on the Avaya. Thus allowing the N900 to be reached (as would the desk phone) and make calls trough the Avaya server. - Use public 3G or private WiFi to connect to the Avaya. Thus allowing the use of the datanetwork for business phone calls. This brings down call cost dramatically. And puts forward savings as a user benefit for this application. (Hence, the application is worth money.) - The capability to hand-over between 3G and WiFi (bidirectional). This is a feature Avaya and Nokia developed jointly in the past and dropped for E-serie phones since E50. - Use the Maemo contact application and its built-in communication options. The so-called Avaya_SIP method would be availble (within the contact application) to connect to regular phone numbers and possibly SIP names as well. - And the tricky bit: The Avaya softphone would fail-over (from datanetwork) to the regular GSM network if the datanetwork is not available. I presum this can only be done upon call setup, but who knows. - There’s a specific feature attached to this fail-over to GSM. It should not be a regular call – cause those can be expensive. It would be a call to specific GSM number, sitting on a GSM box (thus the connection becomes low cost). And the call would automatically send the required destination number through DTMF. Thus allowing the Avaya to set up a second call leg connecting to the destination. Again, I hope this request is fits this community. Would really like to discuss getting this started. And meeting at the conference in oktober is possible. Regards, Jan-Paul
