[asterisk-ss7] Asterisk 1.4.29.1 // chan_ss7-1.4.3 // Digium TE420P Signalling lost

[Diego Reinoso]

Few days ago I lost signalling in my asterisk box.

I am unaviable to capture signalling packets from "ss7 dump", my card its
ok, "ss7 dump" creates the fil but it is empty, I execute "ss7 reset" but
nothing is printed in the file.

I can see all my 4 E1s ok without errors.  This is dahdi_tool output:

 Alarms          Span                                               â

â     OK              T4XXP (PCI) Card 0 Span 1                       â  â

â     OK              T4XXP (PCI) Card 0 Span 2                       â®  â

â     OK              T4XXP (PCI) Card 0 Span 4

Hope someone could give a clue where the error could be.
