I was looking into why web transceiver mode stopped working in DroidStar, and I came across this:
Is there a way that I can restore web transceiver mode to DroidStar?
This API is unrelated to WebTransceiver. Nothing about WT has changed yet.
No IAX connections are working in Droidstar at the moment. The problem has been found but someone needs to build a new apk:
Well, it used to first send a POST with user/pass to portal/login.php, which just returned a 0 byte response. Then it greps the response from portal/webtransceiver.php?node=12345 for "callingName" to receive the token. That worked for months, but now there is no callingName in the response. I never really understood this part very well, is there a protocol doc or source code that explains this part?
All current uses of the WebTransceiver login is a hack. However nothing has changed with the process and functions as you described. Getting back a 0 byte respond sounds like your POST isn't working properly. You need to be getting back the session cookies and using them on webtransceiver.php.
