Fax over IP
Fax Over IP (FoIP)
More organizations are integrating IP telephony into their existing IP infrastructure to reduce costs and lower the complexity of their communications and data infrastructures every day. FoIP can take advantage of these enhancements as well as provide a centralized fax environment with easier deployments and eliminate legacy hardware restrictions. By connecting to Five9SIP’s cloud hosted PBX solution and T.38 enabled gateways from Cisco, Dialogic, AudioCodes, and others, companies can benefit from converged networks, least costs routing (LCR), and virtualization.
Five9SIP’s Virtual Call Center Solution (VCCS) is well-designed to provide every inbound and outbound call center needs which make it a complete solution.
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. FoIP transmits through the same platform as Voice Over IP (VoIP) calls, called SIP. By creating these calls through the IP networks, businesses can converge their data and communications networks into one platform. This allows for lower operating costs by simplifying voice and fax deployments, eliminating costly analog lines, and providing centralized fax environment.
What is T.38?
The main fax protocol, called T.30, was developed to traverse the traditional phone networks, which performs well as these networks provide uninterrupted transmissions. When introduced to the IP network and sent as a VoIP call, latency, jitter, and packet-loss would cause the T.30 transmissions to fail, even though normal voice calls over the IP networks (or VoIP calls) work extremely well. Faxing however, is not as forgiving. To overcome these issues, T.38 was developed and implemented as the new standard. T.38 makes adjustments to compensate for latency, jitter, and packet-loss, by encapsulating and protecting the T.30 fax. Faxing is now able to traverse the IP network and arrive safely to its intended destination.
