GOautodial Open Source Omni-channel Contact Center Suite

Hi,

I'm new to goautodial and installed by following http://goautodial.org/projects/goautodialce/wiki/64bit. I'm using a vps.
Initially my server ip was set to 127.0.0.1Mask:2, and cannot register any softphone. i've run the server update ip pointing it to my vps ip.

I've checked in mysql the conference table and it is showing the correct IP. Ran asterisk -r and saw "Unable to open DAHDI pseudo device". Below is my CLI log
