If you are actually getting what you describe above you should have  
no need to upgrade in order to support 3 or 4 simultaneous calls...   
I have only 384K bit's upstream on my home DSL and that's fine for 2  
uLaw calls. If you switch to GSM or G729 that should allow for even  
greater simultaneous call volume...
