[asterisk-users] Selecing the E1 cards for the call center

[bilal ghayyad]

Hi All;

We would like to build a call center having 2 E1, but we would like to know which card to select:

Sangoma or Digium?

And card type to be PCI express or PCI 5.0V or PCI 3.3V ?

Any advise or special recommendations for the call center?

Regards
Bilal
