When adding a new DUNDi peer in Asterisk, after updating dundi.conf and using astgenkey to create the RSA public/private key pair, Asterisk will emit the following error:

pbx_dundi.c:1331 update_key: No such key 'foo' for creating RSA encrypted shared key for '00:01:02:03:04:05'!

I will be at the 2014 OpenWest conference with a presentation titled "Secure Your VoIP with Asterisk and Kamailio". Looks like they have me penciled in for 3pm on May 9th. Watch the schedule for changes and take a look at all the other awesome talks as well. I've attended and presented a number of times at OpenWest (aka UTOSC) and it's always a great venue.

On a fresh install of Fedora, I tried installing Jitsi but was getting a horrible error. Didn't matter which SIP account I used or how I had my audio set up, I consistently got this error:

TLS has always been enabled, but with a self-signed certificate. I finally went out and got a proper certificate so now I feel better enabling HTTPS as the default. You may still find some HTTP content here or there as I finish the conversion.

EZ Route only supports a single file format for file uploads, which they refer to as "VOX ULAW". There's little information out there when referred to in that way, and EZ Route documentation is sparse. More correctly, the file format is Dialogic ADPCM. If you're really interested in the format, see this site.
