I need to create a simple wholesale switching application that consists of receiving a call via H.323 or SIP, running a custom algorithm and lookup to translate the incoming DNIS into a new number, and the processing this new number through a standard A-Z routing table for termination. The 2 platforms for this application I am considering are Asterisk and Freeswitch. Asterisk has the advantage that I'm familiar with its structure and configuration, therefore I can modify it and make it work quickly. The downside is it is clumsy for wholesale switching and does not scale well. Freeswitch seems to be a better bet given that I would like to scale this application to several thousand simultaneous calls, however I am under a time crunch to get a test application up and running. Can someone suggest to me if Freeswitch would be a good platform for this? If so, where would be the best place to plug in my custom translation routine? Can Freeswitch route signalling only, e.g. RTP/media goes directly from gateway to gateway without passing my network? If so, how can that be configured? I apologize for asking without completely studying all the available documentation and code, but as I said I am under pressure and I was hoping some benevolent individual would point me in the right direction to expedite this. Thank you for any assistance. Best Regards, Chris Ziomkowski
