Dear John,

The documentation on your website is a bit limited. I have some questions:
- Have you implemented an opensource SIGTRAN stack for Asterisk or an 
opensource connector from Asterisk to the proprietary Dialogic SIGTRAN 
- Can you provide some diagrams on your website/wiki of the 
network/protocol architecture?
- Under what licence is the software licensed?

Best Regards,
