[LEDE-DEV] IP Phone ---> SIP ---> PSTN gateway with LEDE/OpenWRT?

[Mauro Mozzarelli]

My requirement is as follows:


 From Location A I want to be able to receive and place phone calls 
using the Public Switched Telephone Network line present on Location B.


On both Location A and B I have BT Home Hub 5 routers running LEDE.

I was wondering if it were possible (and how to) run a SIP server on a 
router at Location B that I can connect to the PSTN for 
incoming/outgoing calls  to route from/to an IP phone placed at Location A.

If this is possible, but not with a BT Home Hub 5, which router would 
support such configuration?


Thank you in advance,

Mauro
