Five rules for five nines

VoIP network designers share this advice for building a fail-proof infrastructure for IP telephony.

  • Test the network: Determine IP traffic bandwidth availability, jitter and delay before deploying.

  • Duplicate: Run redundant call-processing servers and separate them geographically if possible.

  • Duplicate, again: Make sure call-processing servers themselves have redundant processors, network interface cards and disk drives.

  • Patch often: IP PBXs are servers, so keep them updated with the latest operating software fixes.

  • Batteries included: Plan on back-up power supplies for call processors, routers, switches and phones.
