Install G400P card.
With the "gsm show span" command, the result is:
GSM span 1: Provisioned, Down, Active
GSM span 2: Provisioned, Up, Active
GSM span 3: Provisioned, Down, Active
GSM span 4: Provisioned, Up, Active
All modules have a SIM card in good condition.
Before the command "gsm show span" throw:
GSM span 1: Provisioned, Down, Active
GSM span 2: Provisioned, Up, Active
GSM span 3: Provisioned, Up, Active
GSM span 4: Provisioned, Up, Active
I have tried several things:
1. Changing the power of g400p card using pin (molex and adapter).
2. Changing the pci port.
3. Replace the power supply from the motherboard.
4. Update all software. Asterisk, dahdi, freepbx, elastix.
5. CLI commands.
Currently works span 2 and 4 with chips from Colombia, Latin America.
The span 1 and 3 are dead. Place two temporary chips. Origin unknown, came with the purchase of the g400p card.
