The internal card should give you higher reliability as there are fewer 
parts and cables although the external gateways could allow you to have 
redundant servers.

External gateways would also be easier to scale when you need more lines.

Does anyone have experience with the Grandstream gateways? Are they more 
reliable than their GXP2000 phones? Can they actually provide support yet?
