VoIP PBX

The iPAQ 514 is a next generation mobile product from HP. Called "Voice Messenger", this smartphone is distinguished both for its size (107x49x16.3m-HxWxD) and weight (102gr.) for the technical features: tri-band GSM + EDGE, Wi-Fi 802.11b / g, Display 2 " 176 × 200 with 65k colors, 1.3MP camera, Windows Mobile 6, support the SIP protocol.

The configuration of the HP iPAQ 514 is fairly easy through a utility - available on CD in the package of the phone - named "HP iPAQ Setup Assistant" and the phone connected via the USB cable to your PC.

Before you make the appropriate configurations, I updated the firmware with the newest release, 05/02/00, available on the HP support site .

At this point, after setting up the Wi-Fi, we proceed to the SIP configuration:

In the three images above are represented here in three steps to activate the configuration. In image 2, in particular, it shows the sample configuration file that we will use to connect the iPAQ 514 to our asterisk server. Once you have entered all the parameters, and ended on the HP iPAQ Setup Assistant wizard, the configuration will be transferred to your phone.

It is to pay attention to one detail: when you attach your phone to USB cable for PC connection, Wi-Fi smartphone is automatically disabled. After finishing the configuration, you must disconnect your smartphone from the USB cable!

The configuration file sip.conf of asterisk, is as follows:

[300]
type=friend
secret=300
qualify=yes
port=5060
nat=yes
mailbox=300@device
host=dynamic
