Fax over IP infrastructure

Kofax Import Connector requires fax over IP environment to receive faxes over IP networks.

  • The fax over IP supports both G.711 passthrough mode and T.38 mode.

  • The fax over IP system must support either H.323 or SIP signaling.

  • When using H.323, one of the following connection options must be supported:

    • Integration as H.323 trunk like a standard gateway

    • Integration via H.323 gatekeeper as terminal

    • Integration via H.323 gatekeeper as gateway

  • When using SIP, one of the following connection options must be supported:

    • Integration as SIP gateways with optional UserId/Password authentication

    • Integration via SIP registrar with optional UserId/Password authentication

    In both the cases, SIP via UDP/IP must be supported.

  • The IP system must support VoIP using G.711 (A-law or u-law)

  • To use T.38, the mode changes from Voice to T.38 must be signaled using H.323/SIP message (protocol based switch-over). Proprietary methods like NSE-based switch-over (may be used by gateways connected via SCCP protocol to an IP environment) are not supported.
