Fax on Server Edition Linux Servers

IP Office Linux servers cannot terminate T38 fax and therefore, T38 is negotiated end-to-end. When a SIP ATA fax is connected to an IP Office Linux server, the system directly relays negotiation between the SIP ATA Fax and the SIP provider.

To configure Fax on SIP Lines and Extensions, on the VoIP page for the SIP line or extension:

1. Set Re-Invite Supported to On in order to enable Fax Transport Support.
