Configuring Vyatta with an IPv6 Tunnel Broker

October 9th, 2010 4 comments

One way to get connected to the IPv6 network is by using a tunnel broker. The broker provides an IPv4 endpoint to send IPv6 encapsulated packets. This works best if you have a static IPv4 address.

Polycom BLF with Astersisk

March 6th, 2010 4 comments

They are two methods of setting up BLF on Polycom phones. The first gives you idle or inuse status only. A ringing phone will show up with a solid inuse light. The good thing about this method is users can create BLF for extensions themselves. If this is all you need start by enabling the presence feature in the phone provisioning file. Read more…
