  1. Neutron: An Experiment

    When doing Asterisk development I like to have a server around that has test extensions which have defined behavior. It’s useful when testing SIP, dialing, and bridging functionality. Traditionally I’ve run this on a virtual machine on my local network. As of now I’m changing and expanding this. …

  4. #HateGoogle

    I dislike Google. Nay, I hate Google. I used to think some (not all) of their products were cool. I drank the kool-aid and it blinded me. I used their search engine, Google Talk, Chrome, Android, and more. I never looked outside their realm at what others were doing or what was available. …

  7. REST? Who needs a REST ... interface?

    Asterisk has traditionally provided primitive operations using a C based API approach. There has also been the Asterisk Manager Interface and Asterisk Gateway Interface but they do not provide the control that the C interfaces provide. The new REST API (ARI) is an extension of the C interfaces available to allow access to these lower level primitives. …


  8. Gulp! ... I mean SIP! Hi chan_pjsip.

    The chan_sip module has been the defacto SIP module within Asterisk for many (10+) years and throughout that time it has grown and been developed in an organic fashion. This has had the benefit of being pretty much interoperable with anything on the planet but in the end this development strategy has made making changes a bit hap-hazard at times. You never really know if what you are going to change will cause a regression or not. There are other things about chan_sip that make it annoying but I’m going to limit myself just to the above as this post is about chan_pjsip. …
