I'm wondering if anybody has got the new 7921G phone to work with push2phone -application? We have currently that application working with 7920's but now with the 7921, the phone displays "Authorization Required!", and nothing else happens. I guess there might be some big differences, because 7920 uses VxWorks as the operating system, and 7921 uses Linux...

So what happens if you send the authentication? Do you see the phone making a request to the authentication url (see as in a wireshark trace)? and what is the phone's answer for the POST request? Does the request time out or is there an answer to sending the credentials?

Well, the wireshark trace shows the following for the 7921: 4898 > http [RST, ACK] Drw=620 Ack=360, Win=0, Len=0 HTTP/1.1 401 Unauthorized

I did the wireshark trace also for 7920, and it says http > 1170 [ACK] Seq=339 Ack=578 win=64959 Len=0 HTTP/1.1 200 OK. Other than that, I don't see any notable differences.

The error message "Authorization Required!" displays at the same moment in the phones screen, when I push the "Send" button in my application.

Just figured it out... I simply had forgotten to associate the 7921-phones with the "sdkapps" user that I have.

But now I have another problem; We have upgraded our CCM from version 4.0 to 4.1(3). And the pushing doesn't work anymore.

By reading this forum, I have understood that the change from http -> https is an issue here. Mainly, the problem is with the file 'getdeviceip.asp' The line 'return ipAddress;' causes a problem. If I hardcode it to like 'return ""', then it works for that IP-address. But I didn't find any solution how to change that file so that it works with https properly...
