Any mobiles available now or very soon which will support the SIP protocol? Thanks
Well my N80 has a SIP setting menu item under communications if that's any help - not sure what it does - is it for VOIP? I have emailed Skype and they tell my a version for the N80 is under development but would not commit to a timescale.
R.Daneel Olivaw: Skype is just a P2P software application (which obviously need internet access), incompatible with anything else. True VoIP / SIP is totally different, allows you to use any VoIP provider, or even direct connection to any other SIP user if you know the their IP. Regards, Martin
Yes, I can't see Skype being a goer for mobile use via the Net over a mobile metwork. You only need to look at the cost/MB of data to see that it would not be cost effective. However, over WiFi that might be a different situation. However, I agree, Skype is toytown. It works very well for what it is but who is interested in waiting for the computer to boot up every time you want ot make a call. Further, you are tied to one provider and you can't contact SIP phones except via PSTN. Remove 'no_spam_' from email address.
Skype is VoIP. If you definition of "True VoIP" is SIP, then where do H.323 and IAX fit in (as examples).
H.323 is much older so I guess that'll be old VOIP and IAX is much simpler (only one port to worry about etc.) so I guess that'll be new VOIP I thought that any process that runs voice data over an IP network woult qualify (like all the ones that software like Speak Freely and CuSeeMe etc used which I know includes H.323.)
Paul Cupis () gurgled happily, sounding much like they were saying : Personally, I'd say that - yes, Skype is VoIP - but it's a firmly proprietary implementation of VoIP - a walled garden. "True" VoIP is based around open and interoperable protocols. A good analogy is the early days of the internet, when it was busy killing off BBSes.

A better analogy would be with business telephones, which in their direct-wired and IP forms tend to use proprietary signalling to the supplier's PABX (sorry, comms server). SIP could be compared to an analogue line or POTS.
Nokia E60 available now. Doesn't mention VoIP, is a SIP softphone available for Symbian OS ? Pretty steep price, too much for me... Regards, Martin
Look on the nokia website, it tells you bugger all but it woes say that you can make calls using a WLAN and SIP.
Many people these days leave their computer switched on while they are at home. I just checked the consumption of my laptop, it's 24 W. Not much more than my Sky box which takes 18 watts whether it's in standby or running.
I leave at least one of mine on 24hrs, but that doesn't mean I want to rely on it for an incoming phone call. I want to be able to make and receive calls on any line from any phone in the house, which I can do with a small PBX and a couple of ATA's. Ivor
