[Asterisk-biz] Standard practice for termination?

[Chetan Sarva]

What is the standard practice for terminating SIP/H323 traffic as a 
wholesaler? I'm trying to determine whether or not we should proxy RTP. 
The advantage would be that neither party would know about the other. 
Disadvantage is that it would require more resources. We could probably 
sign NDAs/contracts all around but what are others doing?

Thanks
