asterisk, vocal, sip, ser and jabber. oh my.

it’s amazing, when you really stop and think
about it, that it’s possible – with the help of a little elbow
grease – to get a full-featured pbx running on commodity hardware

thanks to

asterisk

:

“To provide a brief introduction to Asterisk’s
capabilities, I will show an example that creates a very simple PBX
with two extensions and voicemail on each. There will be no
external connectivity to this PBX; we will simply be able to call
from one line to the other. This would allow, as an example, two
users to be in separate parts of the country but they could ring
each other’s desk phones. If the called party was unavailable,
voicemail could be left.”

i’ve heard of people using
asterisk

as a “feature server” for existing voip installs powered by
vocal

or
iptel’s SIP Express Router

[ which also features
jabber

integration. ]
