Kphone-4.04 now working for PC-Phone calls
 I've successfully called a real phone in the UK from my Zaurus in Japan. I've only used it with the sipphone.com service, here are my tips to get it working.
[2] I have found that the stereo headphones I have make a perfectly acceptable mic and earpiece. Just use the right ear as the earpiece and the left ear as the mic. The mic quality is not very good, but usable for phone calls. I have also used a Japanese mobile phone "hands-free" set. In this case you also need a 2.5mm->3.5mm jackplug adapter. The audio quality from this mic much louder and clearer than using headphones for a mic. A final idea for an audio setup is to get an adapter used to connect 2 mono mics into a stereo jack, you can plug a mic into one input and an earpiece into the other. I haven't tried this myself, but I think it should work. [3] kphone 4.04 works better than kphone-pi -0.97. Both are able to make calls, but kphone-pi cannot hang up. The application just stops responding to user input once the connection has been made. To terminate the call with kphone-pi you must kill the kppi process, and get the other party to hang up their end. Kphone 4.04 works correctly, just click the Hangup button to disconnect the call. [4] Both kphone and kphone-pi have problems registering with the sipphone.com service. You need to be registered with the service (the client normally registers you with sipphone.com when it starts up) before you can successfully make a call. The only way I have found to get registered is to start a second client when the first client is still running. For some reason the second client pops up a dialog box asking you for your password and then successfully registers, the first client doesn't do this and eventually times out trying to register. This is a bit messy, hopefully someone can figure out an elegant solution. The calls are pretty cheap, and the audio quality is very good, however there is often a delay on the line of about one second and this is quite difficult to get used to (perhaps this delay will not be so bad when calling from the US). Also, the sipphone.com service offers 5 minutes of calls free each day to various countries, very nice, but I have yet to be able to make a free call with them with any client (including their own in WindowsXP).. this may of course change at any time, or be peculiar to my setup, since things in the world of SIP phoning seem pretty volatile. |

When I try to dial out (the numbers I'm trying to dial are like 00441234567890) kphone locks up (using kphone 4.04) but incoming calls work fine. I called it with my cellphone from the UK and there was like 2000+ ms (aka 2 seconds) delay.
Seems cool though, now if I only had someone to call  PS. you can register on http://my.sipphone.com/ |

QUOTE When I try to dial out (the numbers I'm trying to dial are like 00441234567890) kphone locks up (using kphone 4.04) Try dialing 099441234567890 instead (assuming you are using the sipphone.com service), and make sure that you client has registered you with sipphone.com before you try to make a call (you will need to type a password and after that there will be a blue "tick" displayed in the bottom left of the main window to indicate that you are registered (registered here means "signed on/online", rather than "signed up for the service") ). I believe if you do both of these things, it should work (if you installed kphone-pi as well you may want to check you are running the correct program by running /usr/local/bin/kphone at the command prompt. This will provide some diagnosic output that may help too). Oh, you'll need to open/redirect ports if you are behind a firewall (the port numbers are listed somewhere on www.sippphone.com), and also possibly use their STUN server. Dialing *0 should give you a message letting you know "You are behind a SIP compatible router" or "You may experience problems". I've used kphone 4.04 to make some pretty lengthy calls to a variety of real phones all over the world, it's only failed me once, cutting out the audio on one side of the conversation half an hour into the call. The longest call I've made has been 1 hour 20 mins.. with no problems. The delay can vary from almost nothing to a second or so. It probably depends to some extent on your ping time to the proxy01.sipphone.com server (for me about 0.15 seconds) |

Hmm, will this work with a bluetooth headset given one has a bluetooth CF card?
That would be /really/ neat. |

Actually, scrap that, how the hell am I going to get network activity if the bluetooth card is in instead of 802.11b? :-P
Ack, wish there was a way to have wireless + bluetooth (wireless headset + talk to phone) on the clamshells; it'd really fill in a lot of the gaps I'm experiencing now. :-( |

Hi,
Bluetooth and WLAN is possible with the AIRCABLE serial Bluetooth- Adaptor. But how to bring a Bluetooth Headset to work?  Denis |

That would require the headset/handsfree profile which CF / serial bluetooth adapters do NOT support I'm afraid. It's a hardware limitation of the cards, not the drivers.

Oh, damn.
Anybody want a cheap Blue Monkey CF card in Australia? Looks like I won't be using mine much... (Damn it Sharp, why can't you release a clamshell that has wireless + bluetooth [beyond just serial] built in?) |

There are also bluetooth handsfree sets that comes with a bluetooth transmitter that
you plug inside the audio jack..... |

I wouldn't waste your time with kphone, as a project it seems to be virtually dead and it never worked very well anyway ;-( The future (for zaurus users) is Ekiga! And we are nearly there...(perhaps). There is an Ekiga ipk available for r121 but I don't know how good it is because r121 is too difficult (for me) to work with. But I think there is every good reason to believe it will work well - r121 is a 2.6 kernel with alsa sound, and this seems to be important for voip clients running on (relatively) slow processors. Hopefully at some point soon some clever person/people will do one (or more) of the following: - backport the existing ekiga ipk back to beta3 - sort out r121 - persuade the openzaurus people (who I believe have a 2.6 kernel rom which is fairly stable) that they really need to put together an ekiga ipk. Of these options, the first is probably the easiest and most likely to happen, but the end result may never be as good because beta3 is a 2.4 kernel (I think? I'm still on beta1 so I'm not sure.) The second option (I'm increasingly convinced) is never going to happen. The third option is a real unknown! Why haven't they done it already? A working voip client is such a boon (to me, anyway) that I'm at a loss to understand why it doesn't already exist! If I could find well written documentation describing the steps required to set up a build system on a Linux desktop required for making and testing ipk's targeted to (say) a beta3 system... then I would have a go at option 1 myself. Dream on... |
