Skype for SIP name to DDI with Asterisk

When using Skype for SIP trunks with Asterisk a simple an neat way to enable DDI calling for the skype names is to use the “extension” option.
This means that the ‘To’ in in the sip header is set to what you set.

This can then be picked out with a simple little bit of dialplan

exten => 99051000000000,1,Set(CALLERID(num)=${CALLERID(name)})
exten => 99051000000000,2,Set(cNum=${SIP_HEADER(TO):5:6})
exten => 99051000000000,3,Noop(${cNum})
exten => 99051000000000,4,Goto(from-pstn,${cNum}|1)

In the above example we have 6 digit ddi numbers in the context from-pstn.

Setting up the Skype end is as simple as logging into your BCP and then the relevent profile and clicking on the calling tab

and setting as below

Image

This lets you now use one account and have all your BCP accounts have DDI calls directed at the PBX

Installing Asterisk 11 on Centos 6.3

asteriskThis is a short video tutorial on the installation of Asterisk 11, I have included the blog and video in one place for ease of viewing

First, you will want to be sure that your server OS is up to date.

yum update -y

Disable SELinux by changing “enforcing” to “disabled” in /etc/selinux/config. Use a text editor or copy and paste this command.

sed -i s/SELINUX=enforcing/SELINUX=disabled/g /etc/selinux/config

After you update and disable SELinux, you’ll need to reboot.

reboot

Next, you will want to resolve basic dependencies. (More information on Asterisk dependencies.)

yum install -y make wget openssl-devel ncurses-devel  newt-devel libxml2-devel kernel-devel gcc gcc-c++ sqlite-devel

Change into the /usr/src/ directory to store your source code.

cd /usr/src/

Download the source tarballs. These commands will get the current release of DAHDI 2.6, libpri 1.4 and Asterisk 11.

wget http://downloads.asterisk.org/pub/telephony/dahdi-linux-complete/dahdi-linux-complete-current.tar.gz
wget http://downloads.asterisk.org/pub/telephony/libpri/libpri-1.4-current.tar.gz
wget http://downloads.asterisk.org/pub/telephony/asterisk/asterisk-11-current.tar.gz

Extract the files from the tarballs.

tar zxvf dahdi-linux-complete*
tar zxvf libpri*
tar zxvf asterisk*

For the next set of commands it is important to follow the proper order: DAHDI first, then libpri, then Asterisk.

Install DAHDI.

cd /usr/src/dahdi-linux-complete*
make && make install && make config

Install libpri.

cd /usr/src/libpri*
make && make install

Change to the Asterisk directory.

cd /usr/src/asterisk*

In the next step, running the “configure” script will vary depending on whether your system is 32-bit or 64-bit. (Watch the video for more details.) When the menuselect command runs, select your options, then choose “Save and Exit” and the install will continue.

Use this command if you are installing Asterisk on 32bit CentOS.

./configure && make menuselect && make && make install

Use this command if you are installing Asterisk on 64bit CentOS.

./configure --libdir=/usr/lib64 && make menuselect && make && make install

Optional: If you ran into errors you will want to clean the install directory before recompiling.

make clean && make distclean

Once you have an error-free install, copy the sample files from the configs subdirectory into /etc/asterisk.

make samples

Then add the Asterisk start script to the /etc/init.d/ directory

make config

Start DAHDI.

service dahdi start

Start Asterisk.

service asterisk start

Connect to the Asterisk CLI.

asterisk -rvvv

And now you have Asterisk 11 running on CentOS 6!

Yealink release V70 firmware for their T2X Sets

Yealink has announced the release of the latest Firmware V70 for its award winning IP phone SIP-T2X series.

The key feature of this new Firmware V70 is “M7”, also known as the “unified auto-provision template”. With Firmware V70, the configuration files and the deployment methods of T2X, T3X and VP530 have now been unified.

With the deployment of “M7”, end users now no longer need to maintain different templates of T2X, T3x or VP530. In other words, it lowers the learning curve and increases the business efficiency remarkably.

End users can easily convert their old templates of Yealink IP Phone T2X series and T3X series to “M7” through Yealink Configuration Conversion Tool (CCT). Firmware V70 is now available for download free of charge at www.yealink.com.

EFM Leased Lines

Highly reliable 20Mb symmetrical Internet from £350.00 per month

EFM Leased Lines (Ethernet in the First Mile) provides high speed, reliable internet connectivity for businesses who have outgrown traditional broadband, but where fibre base Ethernet services are still too expensive.EFM uses multiple copper pairs to deliver the service. These are bonded together to provide a combined service. By combining pairs you will receive a much more reliable service because if there is a fault with a single wire then the service will just slow down, rather than taking your business off line.In addition, unlike ADSL where the customer is typically responsible for reporting a fault, with EFM the service is proactively managed by the Gradwell operations centre and where a fault occurs, it is quickly spotted and resolved.Finally, if there is a copper wire fault in the BT Openreach network, EFM is provided with “Service Level 4” which aims to have an engineer resolve the fault within 6 hours.

To order EFM, you will need to contact our sales team. Orders are subject to survey and take between 25 to 90 days to be delivered. EFM is available in 1500 of the most popular UK telephone exchanges and you can be upto approximately 4km from the exchange.

To use EFM, BT Openreach will install a number of analogue copper pairs and associated wall sockets. In addition an EFM network adaptor will be installed, which provides you with an Ethernet socket. You will need to have a spare power socket available within 1M of the BT sockets.

Upgrading EFM

It is not possible to upgrade from 2 Pair EFM to 4 Pair EFM or vice versa. Should you wish to upgrade in the future, you would have to cease your line and reinstall.

We can allow some overlap of the circuits to ensure that you do not lose connectivity in these circumstances, but this may be limited to the number of pairs available as exchange capacity may have changed from the time the original order was placed to the time you wish to upgrade.

EFM Pricing

  • Gradwell EFM services are available on a 1 year or a 3 year contract
  • 3 year deal: 50% discount on installation fee
  • The first months line rental and installation fees are payable upon placing of order

Indicative speeds

Like ADSL, the speed an EFM circuit will run at will depend on your distance from the exchange. However, with EFM we can guarantee the minimum speed you will receive1. In our trials, we found that most customers receive a faster speed service than we can guarantee.

EFM is also a symmetrical service – meaning that both the upload and the download speed are the same. This is great if you are making Internet Telephony calls, using video, or sending / uploading large files to the internet.
