__sip_xmit returned -2: No such file or directory

Polycom LogoI've been switching all my devices to run over TLS if possible, but TCP if not. Polycom has been giving me the most grief lately. When changing from UDP to TCP on a Polycom SoundPoint IP 330 or 335, I would continually get the following message in my Asterisk logs:

[Jun 7 10:12:04] WARNING[4747]: chan_sip.c:3905 __sip_xmit: sip_xmit of 0xa0b1338 (len 583) to x.x.x.x:48356 returned -2: No such file or directory

Perl DUNDi Library

I've started work on a Perl DUNDi library. At this point it does some basic parsing of input, but nothing regarding output.

Speaking At OpenWest 2014

OpenWest Logo
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.

TLS By Default

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.
