Hi, I am new to freeswitch and wish to bolt it into our existing network to provide conferencing services. Currently we just use an opensips/rtpproxy configuration for simple proxy switching. However looking at the features of freeswitch it seems to me that I could replace my entire setup with just the freeswitch platform. Would that be a fair comment? If so then there a number of things that I am struggling to find clearly defined in the documentation. 1. Currently our rtp proxy scenario issues a port to come back on but waits for incoming rtp packets to determine the exact port to return rtp on when the caller is behind a nat. Does freeswitch do this, does it need to be configured to work that way? Freeswitch would be on a public address. 2. Currently opensips stores all user info in a mysql database and with 500000+ users is easy to manipulate. How do you deal with such a large user database in a pure xml environment such as freeswitch? Many thanks for any help you can offer. Regards Chris
