N80 / Voip

[dazz27]

Hi does anyone know whether N80 will support this? I see that it has wifi but does this mean that VOIP is a natural consequence? Also, is VOIP still network dependent in some way (like would they bill you for it somehow?), or would it operate in the same way as Skype for example? I see that the E60 has VOIP, and I think that for me this might be a more important feature than a camera.

I get the basics of VOIP but that's about it; not sure about how it would work in practice :( Can you video call on it??

Would appreciate advice from anyone that knows....

It would be awesome if this phone could hook up with your VoIP router (eg Billion 7402VGP) over WiFi and act like a phone...

... oh wait, mobiles actually CAN make calls! I'd forgotten, what with all these 3.2 megapixel cameras and games and internet and SMS... sometimes you just need to take a deep breath!

Haha, dazz27 good question though, I'm willing to bet Skype would be made available for it. PocketPC's seem to be getting good support:

This phone won't be SIP (Session Initiation Protocal) compliant, so you won't be able to hook it directly to your VoIP router, though a version of Skype will be available for it.

But will they be free calls?
I read today that Vodafone UK are launching their hspda network before end of 2006, for mobile pc cards, perhaps for selected phones also. Maybe this will be a rivalry to wifi hotspots? But then definitely NOT free
Isn't hspda several times faster than 3G??

N80 has SIP on it, just like the N70 and N90 does; however it hasn't been confirmed that there would be a VoIP application on it. However, Nokia & T-Mobile press releases seem to indicate that something in that particular area will be happening:

Where are you getting your information from that they are SIP compliant? I'm looking through the press notes, and I don't see any mention of that. And besides, if they were SIP compliant, you would be able to connect it to a SIP router - SIP is only used in the setting up of voice and video calls over RTP, so what purpose would there be in adding something but not using it?

If Pocket-Lint is your only source, then I would question it. I'm not saying I'm definitely right, but if the N80 is SIP compliant, you can use it for VoIP.

The N90 and N70 however, are definitely NOT SIP compliant.

I'll correct myselft here, as reading through the developer docs for S60 3rd edition yealds that the platform is SIP complient and holds an RTP stack, though Nokia is not opening it up through its SDK. Indeed, they have included something and not used it. I apologize for jumping the gun a little.

The E60 and N80, being the first Nokia S60 3rd handsets with WiFi, also makes them the first Nokia devices to indirectly support SIP. Look for an inventive developer to tap that capability soon enough.

Brad,
Nokia is using SIP on the N70 & N90 for the video sharing application; also SIP is used for Nokia's Push-to-talk solution. More details are here:
http://forum.nokia.com/main/0,6566,1_44,00.html

Here's info on the SIP plug in for S60, 2nd Edition - http://forum.nokia.com/main/0,,034-561,00.html - I have heard that video sharing & PTT is also available for the 6630 and the 6680, so we just need someone to write a voip application, using the SIP & RTP stacks.

There's nothing specific about WiFi for SIP, SIP can be run over any radio technology, as long as you have an IP address, so there is no problem with SIP running over GPRS, for example.

Yeah, I'm aware of that - I totally forgot about PTT though. Thanks for the info. Also, SIP is not limited to radio technology, either.

It wouldn't be practical to develop a VoIP client for S60 v2 devices due to the lack of bandwidth though, right?

In any event, back to the OPs question - yes, it is more than likely that a VoIP client will be released for the N80.

Skype is running over 3G. The bandwidth efficiency is related to the codec used, Skype uses a fairly low-rate codec for encoding voice. If SIP VoIP used something like the AMR codec (basic GSM voice coding), then VoIP over 3G should work pretty well.

Would latency become an issue?

to some extent, but I get a lot of latency with normal voice calls as is, when calling overseas ..

Of course, if you talking about when you are roaming, I'd agree. Most of the operators (maybe all?) have deployed a home network solution for GPRS, meaning that when you use GPRS, all your packets are routed through your home GPRS. If you are in Singapore but your mobile operator is Cingular, all of your packets are routed through Cingular's GGSN ...

Cool, but with 3's ridiculous data prices (actually in Australia I'm not even sure you can get GPRS connections execpt for their proprietary Planet3 - I know that you can't browse the web with a normal plan/cap) who knows if it would be substantially cheaper than normal prices for local 3-3?

However, Skype to a mate on the other side of the world using a local WiFi hotspot would be awesome :D

Skype would be so nice to have on my mobile phone.

It looks like the E series are being released real soon now. No sign of N80 yet.

Oh really? So how does that work routing through the home network when you're overseas?:confused:
