You may want to take a serious look at FusionPBX, it makes many of the more mundane administrative and monitoring tasks a lot easier, especially if you're not working with it and making changes every day. It avoids much of the "ok... how did I do that again?" It's a nice tool for learning the architecture of FS as you're getting started, although relying upon it too heavily will likely slow your learning over the long haul. You won't ever completely get away from editing files though, often vi is the best administrative tool available. I bought the original FreeSwitch book in addition to the cookbook and while it is an excellent text with a lot of good information contained therein, there's still some info that's not in there that I'd like to see. For instance, I'm still left with questions about FS' capabilities and behavior with NAT handling in certain scenarios and that info doesn't appear to be very well covered anywhere that I've been able to find - probably due to the fact that FS is still a work in progress. Not many people seem to truly understand the details of FS' NAT functionality, so unless you're lucky and one of the developers who truly understands it has the time to answer your question, you'll have to wade through the code and experiment (which isn't always a bad thing, another one of the many advantages of open source) but that can be quite time-consuming. I was surprised to find that the full original FS book is floating around the 'Net in PDF form, not sure that the authors or the publisher would be particularly happy about that. If any of the AUTHORS want the link(s), contact me and I'll give the info I have to you. If your name doesn't appear on the cover of the FS book however, don't ask me for any links. :) - Phil -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/More-information-on-FreeSwitch...

This is one reason we are doing a second edition to the "bridge book." We are planning on having an entire chapter dedicated just to handling NAT.

That is excellent news. I'll definitely be looking forward to that, thanks for the heads up. In the meantime, are there any plans to add far-end NAT-traversal functionality to FS or is it already there and I just need to figure out how to make it work? In other words: FS | <Internet> -- NAT firewall | SIP phone A, SIP phone B, etc. on the same LAN Phone A calls Phone B and FS tries to route the media from Phone A to Phone B using their external NAT addresses (which doesn't work) instead of just sending the media between the two phones using their internal addresses. Proxying the media through FS works but wastes bandwidth and adds latency when the media could just be going between the two phones. Can FS handle this or is an SBC necessary?

Thanks for the info and feedback!

No problem... I just thought you guys should know about it. - Phil -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/More-information-on-FreeSwitch... Sent from the freeswitch-users mailing list archive at Nabble.com.
