[asterisk-r2] Problem with 2 E1 from diferent PSTN providers

[Juan Cuervo (Quality Telecom)]

Hi

I speak spanish, but Im located in Colombia, in  a city called Barranquilla.
This issue seems to affect to everyone in this city who I know to have 
different telcos connected to the same digital Card.

Im trying to figure out if this a R2 / digium issue and if there is 
something to do at signalling level to solve it.

Moises ,are you there?...any ideas ?? :-)
