The fax call is now able to traverse the network and arrive safely to its intended destination. T.38 makes adjustments to compensate for jitter, packet-loss, and latency, by encapsulating and protecting the T.30 fax. To overcome these issues, a new standard was implemented named T.38. Normal voice calls over the IP networks (VoIP calls) work extremely well. When introduced to the IP network and sent as a VoIP call, jitter, packet-loss, and latency cause the T.30 transmissions to fail. What is T.38 The main fax protocol, T.30 was development to traverse the traditional phone network and performs well as these networks provide uninterrupted transmissions. This allows for lower operating costs, simplified voice and fax deployments, the ability to eliminate costly analog lines, and provide centralized fax environments. What is FoIP Fax Over IP, or FoIP, is a method of sending or receiving a fax through a IP network instead of through traditional phone lines.įoIP rides on the same platform as Voice Over IP (VoIP) calls, SIP.īy placing calls these on the IP networks, businesses can converge their data and communications networks into one. IP network architectures enable HylaFAX Enterprise to quickly switch between VM instances or through remote disaster recovery servers. Centralized Fax Environment with Fax Over IP Advanced FoIP installations can benefit by allowing fax calls to route to a centralized fax server.įax Over IP with Virtualization By eliminating the hardware based fax boards, companies are now able leverage fax in their virtual environments.
