How to set up a SIP trunk in the Asterisk PBX. In my previous article we configured Asterisk with some SIP-devices, and created a basic dialplan so that they could dial eachother.
We also created two additional extensions for test purposes. This time I will show you how to configure a SIP trunk, and add extensions in the dialplan so that the telephones can dial out through the trunk. And if you also have a telephone number (DID) associated with the trunk, for others to be able to dial your phones, through your Asterisk PBX. Test it. Using an OBi ATA as an FXO port or Google Voice trunk for Asterisk or your IP Phone.
If you need an FXO card for your IP PBX, expect to pay hundreds of dollars for a good one.
But what if your PBX doesn't have expansion slots, or is in a different location from your POTS line, or your project is for home/small office use and you require a device that works just as well for a fraction of the price? You're sure to be delighted with an OBi110. If you wish to add Google Voice to your call routing, any OBi ATA will be more than up to the challenge. Setting up your OBi110 as a SIP trunk is easy, and when we're done, the device will still function as an ATA. The following example is based on routing Google Voice calls to and from an IP phone, however the technique is the same for any scenario described above.
Mango's Guide to Configuring an OBi100, OBi110, and OBi202 ATA. We used Linksys ATAs for many years but upgraded to Obihai when we needed a device with an FXO port.
Obihai has outdone themselves and created some devices that are even more configurable than their older PAP2T, SPA2102, and SPA3102. OBi ATAs are deficient in only a few ways - for example a non-configurable jitter buffer, and no way of routing calls based on Caller ID Name or customizing Caller ID Name. Perhaps most disappointingly, the FXS/FXO relay has been removed in hardware version 3.4 of the OBi110, meaning that during a power outage, your POTS line will not function. Fortunately, OBi ATAs' good qualities far exceed their shortcomings and they are what we believe to be the finest ATAs available today.
EDIT: The jitter buffer is now configurable in the latest firmware version for the OBi2 and OBi3 series (but not OBi1). Review of the Obihai OBi110 VoIP device, Part 4: How to use the OBi110 as an FXO port with Asterisk and FreePBX » TechNotes. Important!

Installing The Asterisk PBX And The Asterisk Web-Based Provisioning GUI On Linux. I have read about Asterisk and wanted to test it out as I will be managing/troubleshooting it at work anytime soon, so I thought of getting my hands dirty and getting some basic experience on it.
First, I set up a box with Linux RedHat ES4 but I think any Linux distro would do. Kubuntu/Ubuntu, Fedora or Mandriva would work fine. Here we go: 1) Get linux installed and mark down the IP address of the box. Installing The Asterisk PBX And The Asterisk Web-Based Provisioning GUI On Linux.

Quick Guide to the Obi110. Introduction Obi110 is made by Obihai, a company founded by some employees from Sipura.
Obi110 is a successor to the Sipura SPA-3000, which became the Linksys SPA-3102 after Linksys bought Sipura; Linksys is now part of Cisco, and, the 3102 is now very seldom updated. Until August 2011, Obihai products could only be delivered to US addresses, but they are now available in Europe through Amazon UK (with a hardwired 12V/1A UK transformer...), in Australia through Anyware, and in Hong Kong through Tak Shing.
What does the Obi110 do? The core feature of the Obi110 is to bridge calls between the Internet (GoogleVoice, SIP-based ITSPs, other Obi devices on the Net), the PSTN, and possibly a handset (the Obi comes with a Phone interface to digitize an analog handset.) In addition, it packs an AutoAttendant (AA)/Interactive Voice Response (IVR) to make the Obi a bit more dynamic for eg. callback for cheap/free call while away from home.

My New Landline SIP Setup - SmartPhones, And Its Beautiful. Im going to digress a bit about my sip setup - bare with me. It's interesting how some things can become a distraction you never really wanted.
Some time ago (going on a year roughly?) , i ditched my old adsl router (which did voip and had landline ports for phones) in favour of a x86 box running openwrt. I really havent looked back, and in truth, the voip hadn't been running for at least a year prior to that (my landline comes over the adsl as voip) because the "landlines" i had were cordless phones and the batteries eventually died.
