Toronto Asterisk User Group

Continuing with our series of talks on large scale VoIP systems (Linux High-Availability and the benefits of OpenSER in an Asterisk environment), Mark Warren, the CEO of RedFone will be joining us this month to present a howto on deploying Asterisk clusters with quick and flexible scalability using some relatively new and undocumented technology.

Also, this month we're going to try something a little different and host the meeting at Toby's.

This month, Ovidiu Sas will be speaking on OpenSER from an asterisk point of view -- what it is, how it works, how to configure it, and how to integrate it with Asterisk.

Prerequisites: A good understanding of SIP protocol, and a good understanding of asterisk sip.conf file.

In order to provide a carrier class VoIP service for your clients, your infrastructure must be redundant so that services remain available in the event of hardware failures.

Bill Sandiford from Telnet Communications gives a simple presentation on how to use the Heartbeat application from the Linux-HA project ( http://www.linux-ha.org/ ) to create a redundant Asterisk configuration across multiple servers.

This month, Francisco Palacios will be giving a talk on Aastra’s SIP-DECT solution, a recently launched mobility solution that offers superior levels of interference-free performance, enhanced security, seamless handover and roaming support in a cordless SIP telephone system. This solution can be easily deployed in most Open Source PBX. DECT technology, System architecture, deployment considerations and network sizing/capacity topics will be covered during this presentation. This talk will be aimed at telephony/system integrators, but anybody in the IP telephony arena will benefit from it.

Topic:

This month, Ian Darwin will be giving a talk on the linux-based OpenMoko cell phone. It is doing for the cell phone what Asterisk did for the PBX - disruptively changing the rules and the econonomics. Ian will talk about OpenMoko the project and OpenMoko the hardware and its two known implementations, the Neo1973 phone (which will be demonstrated if all goes well) and the HXD8 (which is not available yet but it's equally disruptive!). This version of the talk (previously presented at Ontario Linux Fest in October) will be aimed at both telephony users/integrators and at software developers.

Topic:

Ovidiu Sas will be giving a presentation on a new package feed that can co-exist with other embedded firmware distributions. It contains bleeding edge packages (such as asterisk 1.4) with manypossible extras (support for unixodbc, net-snmp, jabber).

The presentation covers the following topics:

• why embedded?
• what do you get?
• what's missing?
• how to?
• specifics
• practical example

Topic:

The voicemail application in Asterisk is one of the oldest of the dialplan applications. It is often critisized as one of the less-than-compelling parts of Asterisk, and, because it's functionality is locked up in a very complex, messy and poorly-documented bit of code (app_voicemail.c), no one has the nerve to touch it.

Topic: Murmur!

[murmur] is an audio documentary project that collects and distributes people's stories about specific places. During their daily routines, pedestrians walk past sites marked with a sign indicating the presence of one or more stories, and a telephone number that can be dialed to listen to them. It allows the listener to hear the story of that place, in that place; the details come alive as the listener walks through, around, and into the narrative.

This month we are being joined by Andrew Gillis, the creator of TrixBox / Asterisk@Home and he will be giving a technical talk on TrixBox.

Some background on Andrew:

Andrew Gillis has been working with VoIP since VoIP became commercially viable in 1998. He was a Senior Systems Engineer at several VoIP startups including Octave Communications developing VOIP voicemail systems. He became an independent consultant, deploying worldwide roll-outs of VoIP PBX systems to companies such as Liberty Mutual.
