Nokia N95 8GB – The Symbian IM & VOIP Client Showdown

I’ve had a few emails since writing my previous entry on my favourite list of software for the Nokia N95. People were especially interested in the Truphone application and just how well it acted as an integrated internet phone application. I thought I’d take the oppurtunity to give my quick thoughts on the other chat/messaging/VOIP applications I’d tried since and list the pros and cons of each to get a fair idea of which app best suited which purpose.

IM - The Message Generation

The apps I’ve tried so far are Truphone, Agile Messenger, IM+ Messenger, MSN Live Messenger, Fring, Gizmo and Slick Messenger. Most are Instant Messenging clients that connect to anywhere from 1 network (MSN) to about 5, including ICQ, AOL, Yahoo, Google Talk, Skype, MSN and various others. If each has pros and cons, I’ll list them and give them a basic rating.

Truphone

As you may know from my previous article, Truphone was an instant favourite of mine. It’s a Voice over IP application that’s main strength is that it completely integrates with the phone. I’m still yet to find an application that works so well with the N95′s interface, and at the same time never get in the way with annoying popups, or long processes to connect and make calls/send messages when required.

Setting up Truphone is as simple as installing the app following the instructions on the site, creating an account and choosing an Access point to connect to the server with. Then anytime you’re in range of an internet connection, either via WLAN or 3G you have an icon (a phone over a globe), which allows you to make/receive calls on your specially assigned Truphone number, simplly by Clicking Intenet Call (instead of Voice/Video Call). Like using Skype on a computer it’s not perfect and requires a reliable wireless connection or full 3G for anywhere near normal phone call quality. But it’s crystal clear when its good, and dirt cheap too. In fact, if you sign up and use the service before March 28th, Truphone will give you free calls to most Western countries, both landlines and mobiles.

Pros:

  • Perfect Integration with the phone, no annoying popups, or drawn out call/connection processes
  • Cheap calls and messages
  • Works over both WLAN and 3G internet services

Cons:

  • Call quality can suffer with less than perfect network connection (calling an Australian mobile left a lot to be desired, I’m assuming because of the added latency of the mobile network at the other end).
  • In times of low network service, the constant polling for a better net connection is murder on battery life.

Rating: 4.5 / 5

Agile Mobile Messenger

Agile Messenger (http://www.agilemobile.com/)

I tried Agile Mobile Messenger about the time I first installed Truphone, it really filled in the gaps in regards to an IM Client. Like Truphone the integration with the phone is second to none, and everything really just works. The only thing that lets it down is lack of Skype support, but in reality I can do without it, especially when using such a full featured app. The protocols supported are Google Talk, ICQ, MSN, Yahoo, XMPP, IMPS, AOL and AIM, and whilst surely noone can use all these protocols at once, it seems to cover pretty much all bases at once.

Agile Home Screen

One thing that impressed me about Agile was the extensive options and settings in relation to alerts and connection settings. The ICQ “uh-oh” sound was bad enough 10 years ago, and the two other IM clients which defaulted to this, and were forced to this were a definite down point, enough to make me turn them off and uninstall them. Luckily enough Agile doesn’t suffer from this at all, and has an extensive array of choices to manage alerts, sounds and vibration for incoming messages and events. A top notch message client

Pros:

  • Perfect phone integration
  • Cheap Life time registration
  • Good Support accross pretty much all IM protocols

Cons:

  • Battery life problems whilst constantly polling for connection (see a trend happeneing here)
  • No Skype or other VOIP support

Rating 4.5 / 5

Fring Messenger

Fring Messenger (http://www.fring.com)

I tried Fring after my initial trial of Agile Messenger ran out, and was quite pleased with the results. It isn’t (yet) near as refined as Agile, and this is reflected in its interface, but it does seem to have a fair few of the features to back it up. The thing I liked most with fring was its intercompatibility between all chat/messaging protocols, and I could connect to my Skype account as well as the SIP provider Fring uses. Until recently I hadn’t often used Skype, but I have family/friends back in Australia who use it more than any of the other chat services and I’ve found the voice quality fantastic compared to most other computer -> computer solutions.

Pros:

  • Connects to pretty much any chat protocol, everything I’ve used thus far, anyway (Google Talk, ICQ, AOL, MSN, Yahoo, Skype, Fring SIP service, etc)
  • Like Truphone the Internet/Voice calls are well integrated into the phone, and Skype to Skype is useful

Cons:

  • Clunky interface
  • Battery life death in low connectivitiy situations due to scanning

Rating 4 /5

I’d planned to have a look at the other clients listed at the top of this post, but to be honest I really couldn’t find anything good about them at all. Slack Messenger, whilst having a nice looking interface was chunky, slow, and often refused to connect. The other clients had obvious negatives like connectivity with one protocol/network, in the case of MSN Live Messenger, and the Skype client, though 3 UK’s implementation of the Skype service is great with almost flawless connections over 3G GSM constantly.

Whilst I was recommended IM+ by a few people I found it didn’t compare the other three clients I’ve reviewed, so I’d put it in fourth place. But it’s a pretty even competition between Truphone, Agile and Fring depending on whether you want a fantastic, cheap VOIP service on top of an amazingly integrated client (Truphone), or a full featured and equally well integrated IM client (Agile), or a mix of the two (Fring).

With all this testing of IM/Messaging clients it once again became bleedingly obvious that the only real issue I have with the Nokia N95 is the battery life. I’m used to laptops with a usable battery life of 1-5hrs (and as low as 5 minutes, or a completely dead battery), and it seems reasonable that when used heavily in a situation a high powered phone would have similar life. Despite this, it becomes occasionally restrictive to have to carry around two batteries or be shutting down programs all day just so you can make a phone call on the way home.

To explain why I’m 3 hours late home from work because the pub was calling… of course.

  • Great list, currently I use Skype, but the call quality is not so good. Wanna try others.
  • Impressive piece of information, let me elaborate more on VoIP. Voice over Internet Protocol has been around since many years. But due to lack of sufficient and affordable bandwidth it was not possible to carry carrier grade voice over Internet Protocol. But since the arrival of low cost internet bandwidth and new speech codecs such as G.729, G.723 which utilizes very low payload to carry carrier class voice it has recently been possible to leverage the true benefits of VoIP. G.723 codec utilizes only 6 Kbps (Kilo Bytes/sec) which is capable of maintaining a constant stream of data between peers and deliver carrier grade voice quality. Lets put this way if you have 8 Mbps internet connection, by using G.723 codec you can run upto 100 telephone lines with crystal clear and carrier grade voice quality. I am also a user of VoIP and have setup a small PBX at home. Since I have discovered VoIP I have never used traditional PSTN service.

    Dear readers, if you have not yet tried VoIP I suggest that you try VoIP technology and I bet you will never want to use the traditional PSTN phone service ever again. VoIP has far more superior features to offer which traditional PSTN sadly cannot offer.

    Also It has recently been possile to carry Video alongwith VoIP by using low payload video codecs. I cannot resist to tell you that by using T.38 passthrough and disabling VAD VoIP can carry FAX transmission, but beaware FAX T.38 passthrough will only work when using wide band protocols such as G.711, a-Law and u-Law.

    By using ATA (Analog Telephone Adapter) which converts VoIP signals into traditional PSTN you can also using Dial-up modems to connect to various dialup services. I wont go in to the details what VoIP can offer, to cut my story short VoIP is a must to have product for every business and individual.

    How VoIP Works

    When we make a VoIP call, a communication channel is established between caller and called party over IP (Internet Protocol) which runs on top of computer data networks. A telephony conversation that takes place over VoIP are converted into binary data packets streams in real time and transmitted over data network, when these data packets arrive at the destination these are again converted into standard telephony conversation. This whole process of voice conversion into data, transmission and data conversion into back voice conversation takes place within less than few milliseconds. That is how a VoIP is call is transmitted over data networks. I hope that now you understand basics of how a VoIP call takes place.

    What are speech codec's and what role codec plays in VoIP?

    Speech codec play a vital role in VoIP and codec determines the quality and cost of the call. Let me explain you what exactly VoIP codec’s are and how they work. You may have heard about data compression, or probably you have heard about air compressor which compresses a volume of air in enclosed container, VoIP codec’s are no different than a air compressor. Speech codec’s compresses voice into data packets and decompresses it upon arrival at destination. Some VoIP codec’s can compress huge amount of voice while maintaining QoS which means use this type of codec will cost less because it will consume just a fraction of data network. Some codec’s are just not capable of encoding huge amount of voice they simply consume huge amount of data networks bandwidth hence the cost goes up.

    Following is a list of VoIP codec’s along with how much data network bandwidth they consume.

    * AMR Codec
    * BroadVoice Codec 16Kbps narrowband, and 32Kbps wideband
    * GIPS Family - 13.3 Kbps and up
    * GSM - 13 Kbps (full rate), 20ms frame size
    * iLBC - 15Kbps,20ms frame size: 13.3 Kbps, 30ms frame size
    * ITU G.711 - 64 Kbps, sample-based Also known as alaw/ulaw
    * ITU G.722 - 48/56/64 Kbps ADPCM 7Khz audio bandwidth
    * ITU G.722.1 - 24/32 Kbps 7Khz audio bandwidth (based on Polycom's SIREN codec)
    * ITU G.722.1C - 32 Kbps, a Polycom extension, 14Khz audio bandwidth
    * ITU G.722.2 - 6.6Kbps to 23.85Kbps. Also known as AMR-WB. CELP 7Khz audio bandwidth
    * ITU G.723.1 - 5.3/6.3 Kbps, 30ms frame size
    * ITU G.726 - 16/24/32/40 Kbps
    * ITU G.728 - 16 Kbps
    * ITU G.729 - 8 Kbps, 10ms frame size
    * Speex - 2.15 to 44.2 Kbps
    * LPC10 - 2.5 Kbps
    * DoD CELP - 4.8 Kbps

    Switch to VoIP Today and you will never want to use traditional PSTN ever again.

    Thanks
