Hi Chris, I've recently done a lot of this with FreeSWITCH around a calling-card application - like yours except with a bit of audio prompting and digit collection added. It has a full LCR, etc. I have good intentions (which will, no doubt, add to those already paving my way to hell) about writing this up for the FreeSWITCH wiki, but here's (very briefly) how I did it: - used the outbound event socket interface. I couldn't do everything I wanted to with the switch in Javascript, and talking to the external socket interface in Perl a) meant that I could and b) meant that I could use Perl modules for practically everything else; - wrote something which talked to the inbound event socket interface to track call states; you'd probably not need this for a simple switching application. The LCR that I've implemented is a simple retarded match on an SQL table. It could probably be more efficient, but benchmarks at 100ms peak and maybe 10ms average per lookup across four carriers. Unfortunately we're not running enough traffic for this to be an issue! I hope these are semi-useful; please drop me a note if I can be of more help. Cheers -- Dave

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
