Not seeing max calls that are set in VICIDIAL Trunks?

I am dialing with SIP currently and I have 5 megs of bandwidth & using G729 on all calls. First things I have Max VICIDIAL Trunks set to 80 with 20 remote agents. My campaign is set to Adapt_Taper I am running Asterisk 1.2.30.2, 2.0.x DB Version 1116. Ok now that thats outa the way heres the problem
I start dialing my campaign Vicidial Web interface says there are 80 calls being placed, that number bounces around depending if someone answers the line and it moves between either 60 - 80 at all times. However when I am at the CLI and I do 'sip show channels' I see 40-53 calls being placed. What could cause Vici to have this discrepancy in calls ? I can't see this being a drop ratio problem since it really does say its placing "80 calls" according to the Web interface. I have seen it say at the CLI it was actually placing 80 calls but that was once, never really seen it happen again. Should I check something with my setup ?
