[Asterisk-Users] Performance: Xeon or Opteron?

[Anton Krall]

Well certainly sangoma cards are worth looking into now that they also offer
analog port cards, anybody knows if there is a reseller in Mexico?

|

|much more stable/usable way then does the digium TDM card (and 
|I believe the te110 if it uses the TigerJet pci chip).
