SIP WiFi Handset Flash

[IPOriface]

Hi All,

We're testing a QuickPhones WiFi cordless handset (model QA-342) and all is working well, apart from the FLASH feature. The user guide states that the CALL key is the FLASH key when in a call, however when pressed, it generates the following in sysmon:
347408265mS CMExtnTx: v=206, p1=0
CMInformation
Line: type=DigitalExtn 2 Call: lid=0 id=4388 in=0
Called[E] Type=Default (100) Reason=CMDRdirect
Timed: 19/08/11 11:56

Extn 206 is the digital extension talking to the SIP phone.

Handset doco says that the phone supports RFC2833 for DTMF, and the SIP extension is set to use that. Have also tried with inband with no joy. Turned on & off Direct Media Path, Re-Invite, and have also sacrificed a chicken to the dark gods of VoIP.

All help greatly appreciated.

Do you have "call waiting on" checked at the user?

BAZINGA!

I'm not insane, my mother had me tested!

Nope. Call Waiting is unchecked.

 

[tlpeter]

It needs to be enabled otherwise you cannot transfer a call (flash doesn't work)

No joy. Checked call waiting, rebooted the WiFi handset to force a reregister, and same output in sysmon...

Perhaps you need a different button to do this.
What happens if you press the call button?
What happens if you press it twice within one second?

Pressing the call button generates the Called[E] stuff in sysmon.

Pressing the call button twice generates 2 instances of above.

Holding it down does nothing (apart from single press).

Pressing all other keys generate correct Called[n] (where n is the button pressed, e.g. 1 or 2) in sysmon.

Can paste full sysmon trace if that will help.

You need to be sure that the phone sends the right sip command for flash.
Do you have a sip phone or softphone that works?

Compare the traces with each other.
I have seen sip phone being supporting RFC 2833 but not working as it should.

We've got several different softphones. I'll test flash functionality on them over the weekend and advise.

Thanks for your help. More to follow...
