Hi, Sorry for jumping in without reading the whole thread correctly but I will most likely not have the time to do so before Saturday but would still provide some feedback.
When using Openser as a customer phone proxy, it is my understanding that unless you use the PATH extension you will have problem with firewalls as the packet from Freeswitch will not match the opened IP address for the UDP port. In the scenario where the phone send a REGISTER this way : Phone -> Firewall (create an association) -> OpenSer -> Freeswitch. If Freeswitch answers directly to the packet, it will not match the association on the firewall for the return packet (different IP) and the connection may/will be blocked, so the reply to the REGISTER must come back via OpenSER. Same thing for the INVITE message, if FS tries to connect the firewall directly the packet will be blocked. As well, the firewall mapping need to be kept open with some kind of SIP pinging using OPTIONS - for example - and going through OpenSER as well from the FS server When quickly looking into it a few weeks ago - before I was side tracked, I found that the way OpenSER and FS way of using SIP PATH are not working together very well (I was planning a mail to the list with more info once I checked this more extensively). I can see the point with trying to not use OpenSER and use DNS SRV but you may not always be able to do without.
