[asterisk-r2] Register SIG R2, Line SIG e&m: Unable to setup Asterisk/libopenr2/Unicall

[Oscar Carriles]

I am dealing with an E1 line as R2 E&M
from Telecom Argentina.
Have no previous experience in cases like that-
Hola Moises, espero te encuentres bien.
This combination seems not to be a supported feature,
neither in asterisk/libopenr2 nor in old unicall releases.
Any tip/Trik about the matter would be appreciated.
