Recommendation for Analog ext over long distance

[Antwis79]

Have a small key system installation with Analog call boxes. 2 of them are over the maximum distance allowed. Any recommendations on a ethernet to analog adapter?

Here is the one I recommend. Easy to set up, and they work

Would be good to know the length of the loops. Not sure if a Sip ata fxo/fxs combo could extend to your need or whether some Viking LLA-1 long loop adapters might be needed. Both assume copper is presently there between locations.
