Syntec offer a full range of termination/origination services to users of IP based telephony equipment. These services specifically address the conversion of voice traffic in the IP network to the Public Switched Telephone Network (PSTN). We operate and maintain our own Class 5 switches with extensive interconnect to major carriers. We can originate or deliver IP based voice traffic through VoIP trunking directly to the PSTN network utilising H323, SIP or IAX protocols.
Of course, it is possible to make voice calls between IP endpoints without the use of conventional phone numbers utilising the IP address itself or a convenient alias. Indeed, this is how the popular PC based soft-phone Skype operates. It is when you wish to call PSTN users that complications arise. For example, what CLI (calling line identification) do you set when you do not have a phone number yourself? Most users will select a conventional telephone number to enable people to call them from the PSTN (VoIP call Origination) world and will set this same number when making outbound calls as a CLI (VoIP call Termination).
Business ISDN users will be accustomed to having their own telephone number accessible via DDI from the outside world and will expect the same functionality from an IP based local PBX.
