I have not this issue (I'm using asterisk trunk version), firmware 3.02 for 7920.
Asterisk SVN-trunk-r75505

I have the same Firmware version on my phones as well.  What SVN version are you running?  Also, incoming calls display "Ring-In" even after the call is completed.

I'd be willing to be bet that this has the same cause as ASTERISK-9948

The recent fix for bug 0010291  does not fix the problem with the 7920 phones.  The 7921 phones display the messages correctly.

This small patch fixes the problem.

Needed to call

transmit_displaypromptstatus(s, 0, 0, l->instance, sub->callid);

for each side of the call in skinny_hangup.

By: Jason Parker (jparker) 2007-08-02 11:20:00

The trace I have (let's just assume it's a "normal" call, where the device is offhook) shows the following order:

SetSpeakerModeMessage (SpeakerOff)
ClearPromptStatusMessage   <--- Yep, you're right.
SelectSoftKeysMessage (OnHook)
DisplayPromptStatusMessage (\200\023 - I'm not sure what this translates to)

transmit_callstate() with SKINNY_ONHOOK does:
SetSpeakerModeMessage (SpeakerOff)

That's pretty badly out of order, and we're missing 3 things...I think we need to fix all of that.

Give me a little bit, and I'll come up with a patch.

Uploaded patch.  Give that a try.

It rearranges some of the messages, and also adds the ClearPromptStatusMessage in the OnHook state.

By: sbisker (sbisker) 2007-08-02 13:12:26

That worked.

By: Jason Parker (jparker) 2007-08-02 13:13:59

Just to make sure - before applying this, you reverted your patch, right?

By: sbisker (sbisker) 2007-08-02 13:15:40

Yes, I removed the previous changes I had made.

Make sure we clear the prompt status message on a hangup.
Also rearrange messages to better fit with what a wireshark trace shows it should be.

Issue 10299, initial patch and solution by sbisker, modified by me to fit with wireshark trace.
