Hi thanks Lonnie. Sorry this went into my junk for some reason. 1) Yes this is certainly a problem but I have also experienced problems with no media on calls being hairpinned through Asterisk from the external trunk. This may be solvable with port forwarding however. Maybe I should do some testing on this and specify some known and working router/firewall configurations. 2) I use Open VPN for my external phones so it could be solved this way.
I am currently negotiating with the partner and it looks like they will take option 3 below which I think is the best compromise.

Then again your IT partners go into a dentist's office which were previously sold more router than they needed, it may not seem right to put AstLinux in front of it. My guess is you need to plan for both situations. A couple comments ... 1) If AstLinux will only serve SIP endpoints on the private side, no roaming public endpoints, then being behind NAT is workable, only the trunk is effected by NAT. Always disable any upstream SIP ALG's, almost always bad news. Keep in mind no upstream port-forwarding is needed for this scenario, and always keep the AstLinux firewall enabled for the Adaptive Ban and other protections to be kept in place. 2) Else if roaming public endpoints need to be supported, placing AstLinux at the edge will make SIP easier. AstLinux comes with a dmz-dnat plugin, the idea is to move a pre-existing router from the WAN to AstLinux's LAN with a static IP address and configure the plugin which internally performs a " -j DNAT --to-destination $DMZ_IP " *all* traffic not allowed directly into AstLinux. WARNING - this plugin was written many years ago and has not been tested as thoroughly as I would like to see for production purposes. Though if there are issues with the dmz-dnat plugin they could be remedied.
