Greetings.  I've been unable to figure out how to calculate the DSPs 
needed on a 2800 to terminate a SIP trunk and hand off PRIs.  We're 
going to be handing off 96 active lines to a customer on 4 PRIs.  The 
calls will all be G.711.  The DSP Calculator didn't seem to cover SIP 
trunking.  Suggestions?
