"When you use an SBC that does smart nat traversal methods (if they have sip alg or Stateful packet inspection on) or if they have a integrated device it might not leave the option to turn onn these functions, how useful will it be to you?"
And that's why I thought I would be only using Bria where I can provision "Firewall Traversal" method to be OFF (or Bria Iphone with firewall traversal options off) and let SipXbridge handle the NAT traversal issues. So a smarter SBC, like OpenSBC, would support more NAT traversal scenarios? If this is so, then I need to start learning a lot more about OpenSBC and SipX. My user base is pretty small, less than 10 would be globally roaming and need this type of connectivity. No site to site VPNs. Instead we're simply using ITSPs to provide DID's for our customers in other countries and so that it's a "local" call for the customers. Thanks again!

I've done this before. Trunks on other continents, site-to-site vpn's with analog gateways on other continents, remote users wherever. It's not a reflection on pfSense, but if you want to support remote "mobile" workers and/or a lot of remote users, you need a different SBC device than sipxbridge. Yes, it will work. Yes it will traverse NAT (to a point). What it wont do is traverse NAT in anything other than a basic way, which means you need to reconfigure the remote firewalls of just about every user, to get it to work for them. When you use an SBC that does smart nat traversal methods (if they have sip alg or Stateful packet inspection on) or if they have a integrated device it might not leave the option to turn onn these functions, how useful will it be to you?

Sorry to hijack this thread, but I am not sure I understand the need for OpenSBC or any external SBC with SipX. SipXbridge already handles the NAT traversal issue and is an "SBC" of sorts. I guess I don't if it's a complete "SBC" implementation or not... Are there security issues for allowing "port forwared" connections directly to SipXbridge? I think I've read a thread discussing using OpenSBC to modify the SIP messages and not sure why that is needed? Any examples? Thanks!

I'm not high level enough in this to have any input on the topic. I don't know if that would or would not be a good idea in terms of 'integrating'. I personally like to see things in modular form, not all tied into one single bundle but tied together so that they work very well together, as individual, stand alone 'modules'. I loved using OpenSBC but was never able to resolve the glemlins we suffered. I still believe it was because of my lack of understanding Vyatta so had to move to pfsense. What I can tell you is how badly I would love to see OpenSBC on pfsense though :). Or, even as a safe, secure centos/firewall only setup.
