Hi all,
One of the GSoC students, Pranav[1], has had a focus on Java, Android and account provisioning
He has already done some work on a library[2] to allow mobile apps to quickly deploy accounts from any ITSP
One of the next things under discussion is how to make mobile app SIP account provisioning with QR codes.
Every vendor of deskphones has their own provisioning system, they are all quite different. Some are quite effective, e.g. the way Polycom puts certificates in every phone to avoid the risk of exposing credentials during provisioning or subsequent updates.
Pranav can potentially create:
a) a JAR for inclusion in apps like Lumicall and CSipSimple, Conversations (XMPP) and Jitsi (on both mobile and desktop)
b) a REST service running in Apache Tomcat that interacts with the client JAR
The question is, how should the workflow be structured?
Has anybody seen anything like this already, either for SIP, XMPP or other protocols like email accounts?
What should be in the QR-code, for example, should it just contain a URL or parameters for generating a certificate request?
Once the app starts talking to the URL, what data should be exchanged?
Does the phone need to prompt the user for any data, e.g.a PIN, or can it all be automatic?
Once the account is initially set up, how will changes to the settings be deployed? Should the phone periodically poll the REST server and accept any changes automatically, or should there be a workflow for the user to confirm any changes?
I'm thinking that this facility could work for both per-account settings and maybe per-phone settings, but in the latter case we need to make sure it can deal with conflicts and let the user override anything.
Regards,
Daniel
