Setting up VoIP on Nokia N97 mini

Hello again,

I recently decided to configure VoIP on my (recently) new N97 mini (by the way, I'm really impressed by the quality of the phone. Going to keep it for the next several years, because he satisfies me completely). Actually, I had already configured my SIP-profile some time ago (I have an account at "CheapVOIP"-provider), but I had real problems with using it, because when I tried to use it via "Sipgate", it simply didn't work - I couldn't make any call. So, I decided to fix it and made some search in google. In order to configure the VoIP on N97 mini, you MUST have this file: 

SIP_VoIP_3_1_Settings_S60_5_x_v1_0_en.sis

Earlier it could be downloaded from Nokia site, now (August 2014) you should google for it. Download it and install like any other ordinary application. After you installed it, you should have new menu item "Advanced VOIP Settings" here:

Settings -> Connectivity -> Admin. settings -> Net. settings.

Now you are able to configure VoIP on your phone:
1) configure your SIP-profile as described in my earlier post about N95;
2) now go to "Advanced Voip Settings" menu item. Click on it, and choose "create new service". You will be asked for the SIP profile, which will be used as a basis for the new service. Choose your desired profile and wait a couple of seconds;
3) now if you go to the menu item "Voip services", you will see your new service. 

That's all. Noe you can use VoIP-feature of you N97 mini.

Setting up VoIP on Nokia N95

Some time ago I spent several days trying to configure VoIP functionality of my N95. I installed different aditional software, I registered myself for different VoIP-providers - no chance. Yes, I also tried built-in software. No way, it simply didn't work. I finally I found nice and short manual about VoIP-configuration on the example of "Internetcalls". Following that manual, I could configure my N95 for VoIP.

So, here are steps:
Step 1: configure your SIP-connections
"Menu -> Tools -> Settings -> Connection -> SIP Settings": here you define your SIP profile(s), which later will be used for the phone calls. In my case - I also use "Internetcalls" and "CheapVOPI" - I had to create 2 of them. Important note: don't forget "Domain" field, it seems to be very important. In the case of "internetcalls"/"CheapVOIP" it's "internetcalls.com" or "cheapvoip.com". The rest of the seeting you should get from your provider. Anothe point: field "public user name" doesn't have to be a real phone number (so-called "outbound number), which usually costs money). It also can be a string in format @

Step 2: configure your telephone profiles
"Menu -> Tools -> Settings -> Connection -> Internet tel.": here you just define profiles (set of settings like ussed codecs), which use your SIP profiles for calls. Actually, here I changed nothing except for name.

Step 3: make calls
"Menu -> Tools -> Connectivity -> Internet tel.": this is an application to make internet calls. When you start it, it connects (registers) all available profiles, and you can do internet calls using menu item "Internet call" on the contacts. Here I have to admit, that I have no idea why it connects all profiles (if you several of them), and which one is used "by default". Since I know exactly, which one I need, I simply start application again, and when it asks about disconnecting profiles, I confirm it for the undesired one (and keep right one connected).

That's all. If you have questions, just ask.

Setting DNS server in Linux

Hello everyone,

recently I replaced my DSL modem with a router. After replacement I noticed, that my Internet connection (Firefox/Thunderbird) became very slowly - I needed more than 10 seconds to open a page. Firefox was showing "Looking up " message all the time.

My first idea was to check the DNS server. In the /etc/resolv.conf file I could see that my router is acting as DNS server:
nameserver 192.168.1.1

I checked options to replace that address with the the DNS servers of my provider (Hansenet/Alice, Germany) and found following solution:
1) copy file /etc/dhcp3/dhclient.conf into dhclient.conf.original - to make a backup copy of the file;
2) open dhclient.conf with any editor and make following changes:

* uncomment line "prepend domain-name-servers..." and enter there - comma-separated - IP adresses of the desired DNS servers;
* in the line "request subnet-mask,broadcast-address..." remove part "domain-name-servers" - in this way you prevent DHC client from retrieving the DNS name from the router.

After restarting the networking (/etc/init.d/networking restart) and bringing up your interface you must get you Internet connection at normal speed.

Any comments are welcome!

P.S. Important to notice, that I DO NOT use resolvconf-package.
