My Phone runs CyanogenMod 11. I registered in WhisperPush via the Settingsentry and got the verification code. I do have a Google Account, the phone is new and I haven't installed any apps yet.
Now I wanted to text with my contact (he's using TextSecure) via WhisperPush/TextSecure. When he sends me a message using TextSecure, it's shown to him that it's sent encrypted, but I won't receive any message at all. On the other hand, when I send a message, it's send as a normal text without any encryption at all.
I tried to enter the verification code somewhere, but can't find anything, permissions should be also fine, at least I allow WhisperPush everything.
How can I get WhisperPush to work?
Hint: WhisperPush is integrated with CyanogenMod, so Google Cloud Messaging shouldn't be involved.
Update: I tried it with another contact, who uses TextSecure as well. While I still won't get any encrypted message and the messages I send are still plain text, after unregistering and re-registering from WhisperPush I noticed that I've the public key of my contact in my list, he had mine as well. So it seems there was a key-exchange, but somehow the messaging app(?) doesn't know it can communicate with this contact using WhisperPush/TextSecure.
Update II: I just installed the TextSecure (now Signal) app from the Google Play Store. Works flawless.
