Voice over IP (VoIP) defines a way to carry voice calls over an IP network including the digitization and packetization of the voice streams. IP Telephony utilizes the VoIP standards to create a telephony system where higher level features such as advanced call routing, voice mail, contact centers, etc., can be utilized.

Session Initiation Protocol (SIP) is a peer-to-peer, multimedia signalling protocol developed in the IETF. SIP is ASCII-based, resembling HTTP, and reuses existing IP protocols (DNS, SDP, etc.) to provide media setup and teardown. Since its first publication in 1999, SIP has generated a high level of interest in the VoIP industry, and many people believe that SIP will become the de facto standard protocol for future voice networks.

Most major national operators have switched to VOIP telephony but avoid publicizing this since they continue to charge their customers at the very high PSTN/ISDN tariffs of the past.

ITHAX offers reliable inbound and outbound telephony from/towards all major fixed and satellite networks. For the inbound traffic we may supply local telephone numbers for most major cities worldwide.

ITHAX works over desktops, laptops, palmtops, mobiles, even old PSTN/ISDN fixed or DECT phones, with the use of FXO and FXS terminal adapters and/or DID numbers. PSTN/ISDN technology will very soon become obsolete, due to its high maintenance cost from the side of PTTs, very poor bandwidth usage and limited mobility/interconnectivity.

The term “broadband telephony” used frequently by national telecommunications operators (PTTs), is a nickname of VOIP, a simple marketing trick so that subscribers feel they are being served with a better PSTN/ISDN telecommunication and thus not ask for further price reductions.

ITHAX also offers cloud Fax Server capability. You may send and receive faxes without a fax machine, in PDF format from/to the email account of your choice.

Many services like Conference rooms, queues, IVR, like wake-up calls, alarms etc. are only a fraction of the vast capabilities of ITHAX.

With ITHAX you only pay for what you are using. No hidden costs, no surprises, no bill shocks.
