[asterisk-users] PRI error: link goes down when make calls

[Mc GRATH Ricardo]

Hi.
These becomes from layer 1 issue and could becomes from a wide of  possibilities (telco or Asterisk PRI card).
At first check cables an connectors, on Asterisk could make a loopback and check if problem persist.
On telco should check cable of DSL Modem or whatever provide PRI service.
