Measure the data rate on one call and divide 512k by it for a rough 
estimate..

If you want more accuracy make one call and measure the data rate, then 
two calls and then 3 calls and you should start to see a trend in the 
increse in traffic per call..

My tests on one call showed GSM to use about 34Kbps* so you should 
manage 14 concurrent calls.. As a suggestion look at using the iLBC 
codec which in my test on one call used 25Kbps* which will give you 
close to 20 calls in your 512K connection..
