[asterisk-users] leading ghost 0

Tue Nov 20 08:03:03 CST 2012

Hi Leandro,

I'm sure nobody has added something... tried prilocaldialplan and 
pridialplan but nothing changed.
Question: if pridialplan or prilocaldialplan would work, should I see 
the 0 inside PRI frame with intense debug or it is hidden?

Yes...the technician did it...there is only one cable.

Maybe it is the socket circuitry that has something wrong but I do not 
know ho to check.

Asap I'll be on site I'll do more testing.

Thank you

Giorgio
