Before you configure fax pass-through, perform the following tasks:

• Ensure that you install a software release that supports fax pass-through.

• Ensure that you have a working H.323 or SIP network for voice calls.

• Complete voice interoperability testing with third-party gateways and gatekeepers.

• Verify network suitability for fax pass-through by determining the packet loss threshold. Packet loss and latency are two impairments that can have a dramatic effect on fax pass-through performance.
