Sekiur My Thoughts

With the iPhone Apps store closing in on the 1 billion download mark, its hard to argue that it hasn’t been a huge success and even with the numerous applications available to do just about anything you can think of, there is still room for innovation as long as you keep an open mind and hold on to your imagination.

Standford has made available a course on iTunes that will have you creating your very own application in no time.

Last week I deployed a PBX in a Flash system using SIPConnect from CBeyond. It was so successful that I will start using PIAF in lieu of Trixbox from now on for all future deployments of this type and will replace my home PBX to take advantage of Skype and Google Voice integration.

In this case I used the Aastra 53i (English edition) VoIP phones which when connected to the network, retrieved an IP from the DHCP server, contacted the PBX using mDNSResponse, checked and downloaded the most recent firmware available on the PBX, and downloaded the default configuration which prompts for a user to login. After login in the phone created a config file on the PBX for future restarts.

These Aastra phones come in 2 editions (The English/American edition and the European edition). The power supply for the European edition has different connectors and the display had symbols instead of words. Apart from that they appeared to be identical but getting the European edition to automatically connect to the PBX and configure itself was very painful, having to reset the phone to factory defaults and erase the local configuration multiple times and finally having to define on the phone the TFTP server (PBX) IP address for it to download the configuration.

Two thumbs up for the PBX in a Flash (PIAF) developers who have done a superb job with this distribution holding up the ideals of the original Asterisk@home open source project.

Their documentation was almost flawless although it was difficult trying to find the most recent version of instructions as they are all layed out in bits and pieces across a blog. In pursuit of a perfect install I narrowed down the install to running the iso install, going through the online download and compilation of asterisk and running the update/fix scripts. Now before upgrading/installing any module or OS updates, I downloaded and installed the files necessary to deploy the Aastra phones which is also done by a script and then I proceeded to install/update the software via the FreePBX module admin and finally the OS updates.

Below is the trunk configuration for connecting via SIPConnect to CBeyond from PBX in a Flash:

Outbound caller ID: 5551231234
Never overrride caller ID: checked
Maximum Channels: 6

Outbound Settings

trunk name=cbeyond

allow=ulaw&alaw&gsm&ilbc&g726&adpcm
context=from-trunk
disallow=all
dtmfmode=auto
fromdomain=sipconnect.dal0.cbeyond.net
host=sipconnect.dal0.cbeyond.net
insecure=very
outboundproxy=sip-proxy.dal0.cbeyond.net
qualify=250
secret=[secret-password]
type=peer
username=5551231234

Regitration String: 5551231234:secret-password@cbeyond/5551231234

Note: Notice there is no inbound settings required. DID incoming configuration will determine were each channel from the trunk will ring.
