if interested pls see;
http://www.voip-info.org/wiki-Asterisk+SIP+channels which leads me to 
the next topic. Would it not be practical to start a potential design 
and solution first for SIP based calls using softphones, then moving to 
more traditional and complex phone systems (all VoIP of course)?

Would it not be beneficial then in an office setting to authenticate OGo 
users via LDAP where all the pertinant data can be also stored like 
SIP:/, dial no, telephone id and unit number? This should simply the 
user ID requirements for both OGo and Asterisk as all data is known and 
OGo can talk to LDAP by various means if needed.

ok......more later.

At this point I dont think its needed as I dont see the value. The only 
screens that can be activated are essential my own account 
automatically. So if Billy G. decides to call me my contact data pops up 
with his specific data. Of what benefit is that to me?

Now one the call is complete a log file of time, duration and date are 
provided (which they are by asterisk) and I can add that log to a note, 
task or project then there is value from a user perspective. If I am 
missing something...pls dont hesitate to redirect.
