I think the Sipura is a much better choice than what I got, I wanted to save money and bought an used Tellian that only does h.323. If I decided to use it, I'll have to implement open-h323 and have asterisk do the translation. I've been able to play with asterisk at the moment by editing the conf files and it sure is a lot of work, if you have any progress on quixote, please let me know. Thanks!
