FreeSWITCH Module Update: mod_avmd

Submitted by mcollins on Mon, 06/14/2010 - 23:01

Some of you may be familiar with Eric des Courtis' mod_vmd - Voicemail Detect. He has rewritten this module as mod_avmd - Advanced Voicemail Detect. The new module uses an improved algorithm during audio analysis.
I asked Eric about why he wrote this module (as well as mod_vmd) and why he contributed back to FreeSWITCH. Like most open source developers, he understands that "giving back" can help others as well as the developer:

New Module For FreeSWITCH: mod_osp (Open Settlement Protocol)

Submitted by mcollins on Mon, 06/14/2010 - 22:08

The good folks over at TransNexus have written a new module for FreeSWITCH that implements the Open Settlement Protocol: mod_osp. Jim Dalton from TransNexus describes it this way:
"mod_osp is a module that generates route queries and CDRs in the ETSI Open Settlement Protocol (OSP) format.  OSP is basically a standard set of XML messages for requesting routing and access for inter-domain communications."
Complete information about the OSP protocol can be found at the TransNexus OSP Toolkit page. You may be wondering, "Why OSP? And why FreeSWITCH?" I asked Jim Dalton about the choice to create an OSP implementation in FreeSWITCH. He notes:

Help Us Liberate The Domain Name!

Submitted by mcollins on Mon, 06/07/2010 - 18:37

As you may have heard, there is a cyber-squatter sitting on the domain name. Repeated efforts to contact the person or entity who has this domain registration have all failed. We are now pursuing a dispute resolution with ICANN. Unfortunately this process is not inexpensive for an open source project. Ideally we need to raise $2600US in order to have our case heard by a three-person panel.
