From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.10) Gecko/20050720 Fedora/1.0.6-1.1.fc4 Firefox/1.0.6 Description of problem: The DTMF tones generated by kphone are not correct and therefore not recognized by other systems, e.g. voice mailboxes. Version-Release number of selected component (if applicable): kphone-4.x, kernel-2.6 (?) How reproducible: Always Steps to Reproduce: 1. Dial an automated DTMF-controlled system, e.g. voice mailbox 2. Send DTMF tones 3. Actual Results: DTMF tones are not recognized, ie. the menu system of a voice mailbox doesn't work, making it unusable. Expected Results: You should be able to control audio menus with DTMF tones generated by kphone. Additional info: The DTMF tones generated by kphone are not "clean" enough. The tones are interrupted by short pauses e.g. "tttttttt-tttttttt-tttt....". It looks like the DTMF generator doesn't feed the audio output driver with data fast enough which causes buffer underruns, ie. short silences. I remember that I tested DTMF with kphone-4.0.x on an older FC release (2?) and they worked OK. It could be that they worked OK on kernel 2.4 with OSS, but stopped working on kernel 2.6 with ALSA (also through OSS emulator before kphone-4.1.x).
quick question. what are you connecting to via kphone? a voip provider? asterisk? something else?
I'm connecting to a VoIP provider (sipgate.de).
Do they offer anyway to configure how you send them dtmf signals. dtmf is working for me with my local asterisk boxes. i did have to tell asterisk the the dtmfmode is inband. rfc2833 mode didnt work for me and i didnt try info.
They don't offer any DTMF options in their SIP configuration. I remember that linphone has an option to send DTMF via RFC2833. So I think this can be controlled by the client. What does kphone do? Does it look at some capability reported by the registation server or the proxy?
im not sure exactly what kphone does with regards to dtmf sending. my guess is that it just sends it inline. i will have a look into it more. Im about to file a few usability bugs upstream. this should be a user configurable option. i also found out you can be in a call and close the call window call remains active but you have no way to end the call except to quit kphone. i also have my microphone in in a logitech quickcam, kphone select mic jack on sound card there is no user configurable way to select input devices.
I'm using ALSA as audio driver. Either with a USB headset or a Bluetooth headset via bluetooth-alsa driver.
twinkle has been added to FC6 Extras development. IMHO this bug can be closed now as we should drop kphone from Extras.
Works for me. kphone will stay in extras there is no reason to drop it.
As the reviewer of twinkle, I'm not sure what you're talking about. I put in my effort to give users more choice in software, not replace existing software. I'd reject any motion to remove kphone based on that reasoning out of hand.
