Sapo VoIP On Nokia N95 – The Definitive Guide

Sunday, December 21st, 2008

This information should be useful to plenty of people judging by the amount of requests for it out there on the interwebs.

Sapo VoIP on a Nokia N95. The definitive guide.

Have your phone ready? Got your WiFi router set up and already working for normal net access? Here we go:

1. Go to your user page on the Sapo portal and make sure that you have enabled VoIP, chosen a number and entered a password for it.
2. Get your phone and go to Tools -> Settings -> Connection -> Sip Settings.
3. Press ‘Options’ (bottom left soft key) and select ‘New Sip Profile’.
4. Enter these values on the first screen:

Profile name: Sapo
Service profile: IETF
Default access point: the name your wireless router broadcasts
Public user name: +35130xxxxxxx@voip.sapo.pt
Use compression: No
Registration: When needed
Use security: No

5. Press ‘Back’.

6. Click on the ‘Proxy server’ field, a new screen will appear.

7. Enter these values:

Proxy server address: proxy.voip.sapo.pt
Realm: proxy.voip.sapo.pt
User name: +35130xxxxxxx
Password: enter the password you chose on the Sapo website. This is case sensitive.

Allow loose routing: Yes
Transport type: UDP
Port: 5070

8. Press ‘Back’.

9. Click on ‘Registrar server’, another new screen will appear.

10. Enter these values:

Registrar server address: voip.sapo.pt
Realm: voip.sapo.pt
User name: +35130xxxxxxx
Password: your chosen password. Case sensitive.
Transport type: UDP
Port: 5060

11. Press ‘Back’.

12. Press back again, and again until you get back to the ‘Connections’ screen.

13. Scroll down one place and select ‘Internet tel.’.

14. Click ‘Options’ and then select ‘New profile’.

15. Select your number as just entered on the Sip configurations above.

16. Change the name from ‘Default’ to ‘Sapo’. Click ‘Back’.

17. *Important*: Restart/reboot your phone.

18. Try to make an internet call.

19. Wait a few seconds for the service to register.

20. Hopefully, you are now able to make and receive high quality VoIP calls via Sapo.

If you have any problems at this point, first go back over the above configuration screens and check every setting, especially watch out for where you should have written ‘proxy’ and where not. Also double check the port numbers – note that they are different for the proxy server and the registrar server.

Still have problems? Leave a comment below.

Lifeblog: Day To Day Images (Nokia N95 Camera Test)

Tuesday, September 23rd, 2008

I have just put some new images up into my Lifeblog Images Section. Not usually of much general interest other than to me and to those following my Lifeblog Project, this time they might also be of some interest to those of you who were curious as to the true quality of the much-talked-about camera in the Nokia N95. Hyped, or not? See for yourself.

Here are the images;

First test shot, straight out of the box.
My Labrador/Ridgeback puppy, Juno.

The result of the first rain shower this Autumn here in the Algarve yesterday.
A really interesting and exciting photo of my boots.
An image made this afternoon of a bud on a plant in my courtyard that I have forgotten the name of.
And, finally, my lunch today of scrambled eggs and Tabasco.

For those of you who are indeed more interested in the technical photographic side of things than my lunch; all images were shot with the phone set to the full 5mp resolution. All on auto exposure, auto focus (wait for it to beep and confirm that it has actually found and locked focus – hold the shutter release half way down, then wait for the beep and the screen target bars to turn green before pressing the button all the way – or it will bite you and go ahead without focus), and auto everything else that could be switched onto auto, basically. The only slight exception was the image of the bud on the plant, which was shot using ‘close up’ mode, although other than the mode everything else on that shot was set to auto, too.

None of those images are now as they originally were straight off the phone. All have had some degree of lightness, contrast, colour and sharpness adjustments made afterwards. The negative side to that is that you need to do post-capture image manipulation at all, but such is life with digital. The positive aspects are that surprisingly little adjustment is required with the N95 imaging, and that the phone’s images do have plenty of information captured within them to adjust with.

Overall, considering that this is a phone that we are talking about here, I’m more than happy with the level of quality that it can generally achieve with reasonable lighting. I wouldn’t want to throw away my Nikons and try to make my living with it, but then that is not what it was designed for anyway.

Micro.RogiLife.Com, Finally Searchable

Sunday, September 21st, 2008

It may have taken me a few months to get around to doing it, but now finally and by popular request I can present to you the all-new full! search! function! on Micro.RogiLife.Com.

Now it is actually possible to find stuff, which I admit does seem to be quite a good idea.

Mobile Web Server Update

Sunday, September 21st, 2008

The ‘website served from my cellphone’ experiment (original MWS post here) is going surprisingly well.

Originally I was pretty dubious as to just how stable the Mobile Web Server software was going to be but it has, so far, been almost flawless. Not bad for beta software that is still very much ‘under construction’.

Time permitting, today I plan to alter the stock .css to give the mobsite a different look and so I have copied the css files from the phone to my Powerbook using Nokia Multimedia Transfer, as doing css work is going to be easier on the laptop than on the phone screen.

I have also just switched my N95 over from connecting the MWS via my local wireless LAN to connecting via either 3G or 3.5G (depending on which the phone can find available at the time. It tends to switch between the two – and sometimes back to GPRS – when I am inside and at home as I will be today).

Right now it is connecting via 3.5G most of the time and occasionally dropping to 3G, and my mobsite is working fine with that. I’m not sure if it will be ok should the connection drop briefly to GPRS later as local network traffic increases. I suspect that the phone will struggle to serve the website via GPRS, but time will tell.

Another update soon, but generally speaking the overall stability and performance of the MWS is surprisingly good.

A Live Website From A Cellphone Server

Monday, September 15th, 2008

I have been using some interesting new cellphone software today; Mobile Web Server.

A full description of the software and it’s capabilities is under the link above, but basically it is server software that will run on Series 60 devices such as my Nokia N95.

Using this Mobile Web Server software, anyone with the correct type of phone can run their website or weblog, or whatever, from…absolutely anywhere.

When I say ‘run’ I do not just mean that a person can administrate the website. I mean that they can run the site as in the entire thing, and if they so desired, they can run the entire thing – from their pocket.

There is plenty of in depth information under the link above and in further links leading off there, too.

For my part, this afternoon I put the software and the concept to the test and sure enough, after an hour or so of figuring it all out (it is not difficult to do) here is my ‘Mobsite’ rogi.mymobilesite.net running, as promised by Nokia, totally from my cellphone.*

Excellent.

*Note. As my test website is quite literally running on my cellphone, if I at some point switch the phone off – there will obviously be no website to see. If you do follow the link and arrive at just my holding page there, that will be why. In that case try later maybe, or if you are really keen to see the software and cellphone combo in action contact me via the contact page on this site (link top right) and ask me to switch the server/phone on.
