How To: HDVoice In PBX-In-A-Flash

I recently received an email from someone asking about enabling HDVoice in PBX-In-A-Flash.

I’m about to implement a PBXact for our small company, and I have a nicely running PBX in a Flash in my home. I’m wondering if I can HD-Audio-ize the home rig.

Here’s why I ask. We currently run a SIPX PBX in my company. Everything in that box, all the sound files, are all HD. When you talk to it with an HD endpoint, everything just talks HD. It’s a no brainer.

In my home PIAF/FreePBX/Asterisk, nothing is HD. How do I go about HD-izing it? I have the G.722 codecs all turned on, but I’m wondering if there is an easy way to make all HD-capable endpoints automatically talk HD to each other, and to talk HD to the PBX itself.

Any help is appreciated!

Since PBX-In-A-Flash is built upon Asterisk there’s a a good chance that this is possible, but its way outside of my scope. Given my employers migration to the OnSIP Hosted PBX I haven’t run Asterisk seriously for some time.

Dialing By SIP URI In Asterisk

polycom_ip650_256Barrett Lyon is an interesting guy. He’s the CTO & Co-founder of BitGravity, a company specializing in streaming media solutions for the web.  Long ago I stumbled upon his blog which was then a very simple site. What caught my attention was a post detailing how to use direct dialing by SIP URI within Asterisk. It was unique because he laid out all the relevant DNS changes necessary, and supported the post with a video clip showing the process.

That old blog post has long vanished in a redesign of his site, but not long ago he replaced it with a new version called simply P2P SIP URI Dialing. It’s a good reference on the subject. Highly recommended.

Of course, dialing by SIP URI is really about wholly bypassing legacy telcos and what remains of their TDM networks. It assures that you have IP connectivity between end-points. That simple fact is what opens up the opportunity for wideband calling (HDVoice) as well as video calling and even encrypted calling.
