Many of you would have noticed that at times when you open a packet capture containing RTP from voice calls than there are many RTP packets which are appearing as UDP, Wireshark was not able to detect the UDP payload as RTP
If you right click on any such packet and select ‘decode as’ RTP than wireshark correctly detects packets as RTP streams, however if you have like 100 undetected streams in a capture than it becomes a headache to manually do this step for every stream

Decode and Play G729 on Windows
Wireshark has a very nice feature that lets you play and listen to G711 streams present in a captured traffic dump file, unfortunately Wirehsark is not able to directly decode G729
However, you can still manage to play and listen to the G729 stream by using the following steps
1) Open the capture file using wireshark
2) Go to Telephony > RTP > Show all streams
3) That will open up a windows listing all detected RTP streams, click on any stream
And select analyze
4) On the next windows click on ‘Save Payload” let the format be as ‘raw’, lets name the file as ‘stream.raw’

If you make frequent calls to other states and even other countries, you may wish to look into an Unlimited Long Distance plan. Some service packages are made for residential locations as well, and can even have a secondary package for home-based businesses. Others are corporate in nature and can reduce Unlimited Long Distance phone bills for businesses by 70 to 80 percent.
There are a few opportunities for businesses and companies that constantly call long distance every day of the week. For example, a phone company may charge a flat fee to telecommunications companies and any business that uses an auto dialing system as payment for Unlimited Long Distance calls. However, these plans are usually for high-volume, multiple-operator companies and not for individuals or individual offices that make a few Unlimited Long Distance calls a day.

SMS Preview App lets you to preview the new SMS messages that you have just received, basically is just flashes the text of new SMS on your screen for sometime
However, SMS preview app is not working on E-72 as per desgin and instead of making your life easier, it is making it worse
When the new SMS flashes on your screen, SMS preview just locks the screen and pushing any button does not make it good away, if your phone locked than you are even not able to unlock it and it gets really annoying
I hope the developers fix this problem in next update, most of the SMS are very short and there is no point in occupying the screen for long intervals of time!
If you have installed the Google Mobile Search utility on your mobile phone than you would have noticed the message “Press ‘c’ to search” on your screen.
Now, just like you, I also though that the ‘c’ means what it says, but no,
The ‘c’ does not mean the character ‘c’ on your keypad; neither does it means that you press the space bar or the middle button of your mobile phone
The ‘c’ here, stands for clear, so you have to press the backspace (or the key by which you delete typed characters) key on you keypad to activate the Google Search.
You might have a DSL modem and router and wireless access point integrated as one single unit.
This ADSL wireless router is meant connect to the internet via DSL and at the same time provides you wireless connectivity. If you don’t want to use your DSL connection but have some other means of connecting to the internet like Cable or WiMax than the situation can become a bit tricky and these devices might not always work.
Anyway here is the procedure which can be used to connect a TP Link Wireless ADSL2+ Route TD-W8910G to a external WAN.

To utilize Voice over IP (VoIP), you need a high speed Internet connection and an analog telephone adapter (ATA). The ATA is the device that allows you to connect your regular telephone to the Internet. You can purchase these from a retailer or use the one provided by the VoIP provider when you sign up for their plan.
The ATA connects to the broadband Internet jack in your house. Since you likely won’t have many broadband outlets in your home, you’ll likely want to use a multiple handset cordless telephone to conveniently use your VoIP service throughout the house.
There is only one potential downside of a VoIP service compared to traditional dial up services. The VoIP services requires both power and the availability of a high speed Internet connection to operate. If either of these are down, the VoIP service will be unavailable, a limitation not faced by traditional dial up services. On the other hand, most people have a cell phone they can use as a backup so even a power or Internet connection outage wouldn’t be a problem.

Some of the phone systems I’ve looked at such as Shoretel’s implementation require a license per extension. Asterisk on the other hand, does not require any cost for the software, only the price of the server, any switches need, and the phones themselves. This is another big point for the Asterisk system: You can use quite a variety of phones with the system pretty easily. From what I’ve seen the Cisco 79xx line and the Polycom SoundPoint 30x and 50x are the best phones around. The Polycom seem to be quite a bit cheaper for the same feature set as the Cisco’s though. Currently, I’ve got a test implementation running that took about an hour to set up, and tested with soft-phones and a pay as you go account from Iaxtel.

I’ve been playing with as a possible solution to use Polycom 501 IP Phone with asterisk.
I’ve been looking into the usability of the Polycom 5xx series phones as well as a few others, and now have two phones in house to play with. The phones out of the box are nice, though, I’m not too happy with the ring tones that are available with the phone itself. To me, it seems like this wouldn’t be a normal office phone that anybody would want to use, the rings are quiet, and not very alerting. I might be a little biased in this opinion due to the fact that I work in operations, BUT nonetheless, a ring is one major part of the feel of the phone. That said, there are quite a few nice points about the phone worth mentioning. First off, it’s usability with Asterisk is pretty damn good. Right out of the box, the directory is easy to configure(via xml and tftpboot), config for the phone is xml, and remote rebooting the phones works flawlessly. I must say that it did take me a few clicks to find out the procedure to do this, as I’m new to both Asterisk and the Polycom phones. For those interested, the Polycom’s use sip, and inherently the sip notify feature of asterisk, which has a builtin script for Polycom phones in particular(there are some others as well, search for “sip notify”). Also, the Polycom’s configuration is pretty easy to sort out as well, assuming you have the correct options for dhcp setup(i.e. boot server, etc) config is pulled off the tftp server immediately.
Nice for something like this to work right out of the box!
I have had my current laptop for about 16 months, in the begining the laptop had a backup time of 1.5 hours but now it has quickly fallen down to only 10 minutes
A bit of investigation revealed that I need to re-calibrate my battery to improve the performance.
Following are the steps that you need to follow
Fully charge your battery
Go to your Control Panel:
Start->Control Panel
Open Power Options
On the Power Schemes drop box click on “Always On
Click on the Alarms Tab and uncheck the low battery alarm, and the critical battery alarm
Now unplug your adapter from your computer and leave it on until it loses power and shuts off by itself
Do not use your computer during this process.
