It won't work out beautifully, but it will work out ugly.
And all because the LG ARIA SOHO, alas, is a banal analog craft in the porn elephant genre of the 90s. Therefore, you will have to attach a 16-port FXS border SIP gateway to it and teach Sohu to call other numbers through it. The maximum number of external lines for Soha is 12, so 4 ports will not be used.
With the NCP-1000, everything is simpler, it famously provides up to 64 external SIP sessions, although, knowing the customs of manufacturers of proprietary solutions, I believe that some licenses will have to be purchased.
Most likely, alas, even on NCP it will not be possible to make a single dialplan, and the numbers on the sites will have to be scattered "by the first digit" - 1XXX and 2YYY.
I believe that the NCP SIP trunk will agree to build it, but whether the FXO border on the second site will be able to dismantle it is an open question, resting on its cost and education.
The issue of closing telephone connections between the sites will also, apparently, have to be solved by setting up routers in both sites. Which, by the way, if these are worthy representatives of the family of routers, should not put them in a difficult position at all.
I believe in general that, looking sensibly, it would be cheaper to throw out Sokha to an analog grandmother and use a system unit with Asterisk. He can definitely be persuaded to do anything. And you don't have to pay for licenses.
