Remember the days of Winamp, that funky, light (~v2 anyway) little MP3 player? It was the ultimate accessory on every geeks tools belt, along with ICQ, mIRC, Netscape and possibly Eudora (though I never cared for it).

Its truly looking awesome collection of IM utilities for Nokia N95. But sometime that happened that due to low signal quality, such kind of apps does not work properly.

I sometimes feel nostalgic when I remember my first car. It was a Toyota Corolla, and it was a gift from my parents. I don't remember any major problems with it while I was in college. It also taught me the value of regular visits to the mechanic to keep it in good working condition.

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

Absolutely, it was a terrible bit of hardware, I do feel a little bad about selling it on to the next guy for £100 a few months ago though. Good Riddance!

I would never buy one of their products again, it is the most useless piece of shit on the planet, I installed one for a client and one for myself, they have both been completely unreliable
I would recommend anyone to stay away from their products if you are looking for reliability, it works when it feels like it, one day it appears on the network, the next day it's gone, total fucking crap!

No problem Tyrone.

Stay tuned, I've got more coming soon, along with a few alterations to some of the apps (and my opinions of them) in this post.

Oh, and I'll fix up the blog/formatting one day too :P

I've not tried to build my own ROM (there's already so many cooks as it is), but have a couple of handy little scripts which help the flashing process. it copies all installed apps from /system/app and the apps local DB's in /system/data to a backup area which are then copied straight back on after flash is complete.

Re: HTC Hero – The perfect setup

Justin Megawarne — Mon, 18 Jan 2010 01:50:44 -0000

Have you played much with making a custom ROM? As in, hacking some of the source and getting only the stuff you want in there?

Definitely gonna have to look at Advanced Task Manager and SetCPU. Anything for undervolting? :P

Re: HTC Hero – The perfect setup

They should be all free except for Advanced Task Manager, and there are free alternatives to that as well. definitely though the combination of Screebl and Locale I think has been the best thing that I rely on all the time.

I firmly believe that Locale should be the defacto standard (maybe included in Android itself!?) and any apps which drain battery life or something should publish plugins for it. I'd love to get in a situation where I could turn off say twitter updates at work (to cut down on time wastage or turn down the frequency of gmail sync if the battery was running flat, etc etc.

I like to keep my phone as clear as possible too actually, the less crap, the better!

About the blog, yes I know I've got some fixing to do, its very rough around the edges, I've just not found the time yet!

Re: HTC Hero – The perfect setup

Henry — Tue, 12 Jan 2010 20:14:24 -0000

Yo, which of those apps are free, and what do the ones that aren't free cost? There's some good stuff in there that I'll probably try out.

Have to disagree on the chomp sms stuff though - I really like the base Android sms client. I've not used Chomp or the iphone one extensively, but from the short play I had on a mate's iphone, it looks all shitty and cutesy without much benefit.

Mind you, since I don't use any sort of apps2SD, I try and keep my setup as lean as possible to keep things running smoothly. I'm looking forward to upgrading from the G1!

Also the blog seems to have some formatting issues on IE7. There's some text overlayed on the blog post - I think it might be from your footer or something?

I'm loving Balham though, by the way, great area!

I have the same dilemma, although I'm not even going to bother buying it to see.

I'm thinking the next PC I buy will be an HTPC, and eventually a console to go along with it.
