How to connect Nokia e71 SIP to Asterisk?

Today I tried another wonderful feature that built in this Nokia e71, VoIP SIP client. After several testing, it's works! Now, my e71 not only as my mobile phone but also my "mobile office extension phone"! It become an Unified Communication Device with combinations of several features e.g. mobile phone, emails, web browser, extensions phone, instant messenger client etc.

In order to connect your Nokia e71 SIP ( Internet Call ), there are some configurations are needed in your Asterisk Server. You may refers to my sip.conf settings as below :

callerid=device <1010>

You may also like to configure the "realm" in the sip.conf under [General] context, else you may leave it as default which is "asterisk".

Remember to restart your SIP service to avoid getting Error 400 later in your asterisk debug.

The next step that you need to do is configure your phone ( Make sure there is Internet Connections ).

Step 1:

Go to "Menu"-->"Tools"-->"Settings"-->"Connections"-->"SIP Settings". Then, click on "Options"-->"Add New"

Profile name: <to be defined>
Service profile: IETF
Default access point: <your wifi access point>
Public user name: sip:<SIP user>@<domain or IP address>
Use compression: No
Registration: Always on
Use security: No

[Proxy server]
Proxy server address: sip:<IP address of your asterisk>
Realm: asterisk or <realm of your asterisk>
User name: <SIP user>
Password: <secret>
Allow loose routing: Yes
Transport type: Auto
Port: 5060

[Registrar server]
Registrar server address: sip:<IP address of your asterisk>
Realm: asterisk or <realm of your asterisk>
User name: <SIP user>
Password: <secret>
Transport type: Auto
Port: 5060

Now, you should able to see that your SIP is Registered.

Step 2:

Go to "Menu"-->"Tools"-->"Settings"-->"Connections"-->"internet Telephone Settings". Then, click on "Options"-->"Add New Profile"

Name: <to be defined>
SIP profiles: <previously defined profile>

Try to make an Internet Call by select "Options"-->"Call"-->"Internet Call" after key in the telephone number.

Use your GMail as your Online Storage

There are several ways that you can use your GMail account as your Online Storage. Gmail Drive is one of the third party software to make your Gmail as storage.

GMail Drive is not supported by Google. It allows a user to access a virtual drive stored in a Gmail e-mail account by causing the contents of the Gmail account to appear as a new network share on the user's workstation.


After you installed the GMail Drive, you will find a GMail Drive in your windows explorer. Right click on this new drive and choose Login As. Enter your Gmail username and password when prompted. It is recommended that you create a new Gmail account for this purpose so that you can keep your existing Gmail account safe. After logging in, you can now copy, paste and create folders in this new Gmail Drive just like any regular Windows folder.


Besides using GMail Drive, you may also use GSpace Firefox extension to access and utilize the GMail account as online storage.


**Try at you own risk ** These applications are yet to "certified" and still under testing.

IPv4 address Exhaustion

Internet Protocol fourth revision ( IPv4 ) exhaustion referring to the decreasing of the available of the allocations for IPv4. This concern was started since 1980s when the Internet started to grow dramatically. There are many actions being taken to resolve and secure the situation, methods like classful network, C.I.D.R. , D.H.C.P. , network address translations (NAT) and these actions have significantly delayed the exhaustion.

The green grass in the picture below shows the available IPv4 ( but I not sure on the updated, the map was actually created some time ago ) :


Let's see the dramatic growth of the IPv4 usage :


In order to resolve this problem, the experts have introduced the Internet Protocol revision 6 and IPv6 has a much larger address space than IPv4. The IPv6 is built up with 128-bits long and segmented into 8 groups of 4 HEX characters. 50% of it represent the Network ID while the other 50% represent the Network Host.

empireTower The experts believe IPv6 will have need a very long time until it is exhausted again! A rough calculation, there are about 350 Trillions Trillions Trillions IP Addresses are available!!! There is someone making the assumption if ONE IPv6 equal to an Atom, then it would takes up more than 1 millions of Empire Tower to represent the entire IPv6 block!! Impressive right?!


A Quote from wikipedia :

IPv6 is intended to be the long-term solution to the IPv4 address shortage. Instead of a 32 bit address, with 4.3 billion possible hosts, IPv6 uses 128 bit addresses, providing 3.4×1038 or 50 octillion for each of the roughly 6.5 billion people on Earth.

IM using your mobile

IM, so called Instant Messenger, i.e. MSN, Yahoo! Messenger, Skype, Google Talk etc. is a tool that transform real time communication on text-based form between two(2) or more individual over the IP data network. It has become an important communication tool in our daily life.

Todays mobile phone has been embedded with various form of data communication transport methods like GPRS, GSM 3G, HSPDA, and the most cost saving method --> 802.11b/g WiFi. And I believe the mobile phone which built in with the 802.16e WiMAX chipset will be on the market very soon.

Thus, it also means that you can have your Internet data communication ON with you wherever you are, and full mobility! The most important thing is that with the WiFi network meshed around the cities in the world and WiMAX network which start growing everywhere in the world! And it is FREE or should I call it unlimited usage on a fixed charges.

Today, Windows Live has ready with Messenger Mobile client - Windows Live Goes Mobile. You can chit chat via mobile, check your hotmail, even MSN "spacing". Check it out...


I prefer another application called Fring. The greatest thing for Fring is it built in many messenger clients like MSN, Skype, Google Talk, ICQ etc and the greatest client is the SIP client. With this, now I can have my office extension number following me whenever I am, and it is a mobile extension phone!

How Fring work?


Check out more from Fring's website.

Let's see and now my Nokia e71 is equipped with Fring also!! haha...

Hard reset (Default) on your Nokia e71

There will a time, you will find that your phone works slower and slower...or even hang!! Before you bring it to the center or technician to re-format it, you can maybe save your money and try perform a hard reset ( default/factory reset ).

Please always remind to backup your configurations and data FIRST! You can find the backup function in the Nokia Phone Suite application. Also remember to sync your address book either to Micosoft Outlook, OE or any raw data format. For SMS/MMS backup, you can change the storage location from phone memory to your external memory card.

To change the SMS/MMS storage location :

  1. Go to "Menu"-->"Communication"--->"Message"
  2. Click on "Options"-->"Settings".
  3. Select "Other"
  4. Change the options for "Memory in use" to "Memory card".


To hard reset :

  • Click " * # 7 3 7 0 # ".
  • Then it will request for your Lock Code, use "12345" unless you had previously changed it.

Everything will be back to the factory settings. What you need to do now is reinstall your applications, sync back the address book and restore the configuration data.

Free WiFi in Penang : Wireless@PENANG

Further to the Wireless@KL which I personally had an bad experience on it, never able success to get online thru it or even browse to it portal page! ( Just keep showing "under maintenance" ) It happen in most of the wireless@KL in the heart of the Kuala Lumpur!


Back to the topic, on this day 19th Sept 2008, Wireless@PENANG is launched by the Chief Minister Lim Guan Eng. Penangites is going to enjoy free wifi wireless network within Penang! Their target to complete it within 18 to 24 months.

It sounds great, isn't it? You can now login to your messenger tool like MSN, Yahoo! all day long using Wifi instead of expensive and unstable crap 2G or 3G network! You can even make voice call to your buddy using skype and it is all Free! Cool!

Again, back to the realistic. How stable and how brilliant the network maintenance will be ? How the team would handle the 2.4GHz RF interferences and hand-over ? It would some of the challenges ( there are actually more.. ) that the operator and the network builder have to iron it...

If you still encounter the same problem after performing the steps above, try the steps below :

  1. Click ‘Messenger Service’.

IEEE 802.11r WiFi roaming standard approved!

The newest Wi-Fi protocol, 802.11r, which has become the de facto "Wireless VoIP standard", is now a published standard of the Institute of Electrical and Electronics Engineers (IEEE) standards board.

ieee802-11-logo On this day, 29th August 2008, the IEEE has formally announced that 802.11r is approved. According to Wikipedia, IEEE 802.11r-2008 or fast BSS transition (FT) is an amendment to the IEEE 802.11 standard to permit continuous connectivity aboard wireless devices in motion, with fast and secure handoffs from one base station to another managed in a seamless manner.

The arrival of 11r is timely. Voice over Wi-Fi is expected to generate increased interest as more dual-mode Wi-Fi/cellular solutions are delivered this year. 802.11f provides a fast enough hand-off for data services, but that can take a second or two if cryptography is being used, so 802.11r was kicked off in 2004 to provide consistent connections. The handoffs take place in less than 50 milliseconds, rather than the several seconds needed to negotiate a secured connection.


Given the need to integrate with 802.11i security and 802.11e QoS standards, developing a workable standard for fast roaming is challenging. Not surprisingly, 11r defines a complex architecture, though one that is not expected to require forklift upgrades of existing hardware. But getting all the software right will be difficult.

Mobile Number Portability in Malaysia

After YEARS of discussing this topic, MNP, by the MCMC. Finally, it will be implemented on 29th August 2008 ( Friday ). It would started for Pre-paid user and followed up by Post-paid user in a couple of weeks. The nationwide launch for the MNP service is in October.

With the MNP implementation, the mobile user no longer 'tight' with their mobile service operator.  You will have the convenient freedom of switching to competing mobile service operators while retaining your respective phone numbers. It means that you can switch any operator from Digi to Maxis or Maxis to Celcom etc. with your phone number e.g. +6016-XXXYYYY remains the same!


There will be a RM25 charge everytime the MNP is used to switch to a new operators.

  • Edit the resolv.conf and replace the nameserver to your DNS server.
  • Save and copy the resolv.conf to C:\Windows\System32\drivers\etc
  • Go back to C:\dig, right click the doshere.inf and select Install.
  • Edit the Environment Variables ( can be found under [Control Panel]-->[System]-->[Advanced] )
  • Edit the "Path" and append "C:\dig" at the end of the line.
  • Now, you should be able to use the DNS query from command prompt!


Example on DNS query :

  • Show the name servers that controlling .my domains
    • dig my. NS
  • Show the name servers that controlling
    • dig NS
  • Show the Mail Exchange for
    • dig MX
  • Show the IP address for the web,
    • dig
