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!

Thanks,

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.

Nerd Uno Dishes Out Advice on SIP Security

Ward Mundy over at Nerd Vittles has a great post today about SIP security. It’s entitled The Incredible PBX: Adding Remotes, Preserving Security. If you run an Asterisk based PBX you should probably read this. Now!

Ward’s advice really rings true (sorry for the telecom geek pun, it couldn’t be helped!)  His “Baker’s Dozen SIP Security Checklist” makes perfect sense. That doesn’t mean that I can’t add my own two cents.

Into The Great Unknown: The Dreamwave D28P

D28P-200Earlier this week Asterisk guru Ward Mundy pointed out an E-bay auction for a phone that looked kinda familiar and purported itself as offering “HDVoice” – the Dreamwave Networks D28p. A quick Google online revealed that Dreamwave Networks are based in New Jersey, and their web site looked to have both a brochure and some documentation about the device. I even found a tutorial on setting up the phone for use with various Asterisk distributions.

Nerd Vittles Guide to ISN

Aastra_9480i_bl_270x270Over at Nerd Vittles that Asterisk Guru Ward Mundy has posted a great how-to implementing ISN lookups with his popular PBX-In-A-Flash Asterisk distributions. It’s a great overview of ISN and ITADs, including Freenum.org.

ISNs are a novel approach to bridging the gulf between the worlds of legacy phones with traditional phone numbers, and the realm of SIP URIs. It’s a way of dialing something like a normal number and having it automatically be resolved to a SIP URI. This is easily implemented using Asterisk, especially when Nerd Uno shows you how.

All of this is an approach to transitioning from our current state into a time when SIP URIs are more commonplace. That would imply that more of what we think of as “phone calls” would transit a pure IP network. That fact is a major enabling mechanism for such improvements as wideband audio & improved call security, amongst many other things.
