Asterisk SIP Trunk Settings – Vestalink

Vestalink is a new SIP trunk provider that has sprung up as a replacement for Google Voice trunking within Asterisk servers. They offer a very attractive pricing plan with 2000 mins/month going for $39.99 per year, and unlimited plans at $49.99 per year! This provides a single DID along with two SIP channels for the possibility of holding two simutanious calls from one account (call waiting). The folks over to Nerd Vittles have written up a great guide to getting the service working with FreePBX, however I was hard pressed to find any documentation on how to get this working under a standard Asterisk server using only the CLI. Applying the Nerd Vittles FreePBX configuration to Asterisk CLI did not work out of the box. After some messing around I was able to sucessfully register my Asterisk server to my Vestalink account, and I have provided generic configurations that should help anyone looking to integrate a Vestalink SIP trunk with a vanilla Asterisk installation.

AsteriskNow – How To Change The Default FreePBX Password

AsteriskNow is a full blow free turnkey PBX Linux distribution based on CentoOS that can be used in many different types of telephony applications. It is very easy to install and initially setup however changing the default freepbx password can be a bit challenging since there is no link or menu anywhere in the interface to do so!
