As enterprises continue to migrate to Voice over Internet Protocol (VoIP), service providers are offering value-added voice services that will transform the way we use the broadband network. One such service is Session Initiation Protocol (SIP) trunking. SIP trunking is expected to grow at a rate of 58.4% over the next six years (Frost & Sullivan, 2006). The service will enable an enterprise to ...

A Real Fax and Modem Solution for Asterisk®
Overcoming the Different Clock Sources Challenge
Since Asterisk's early days, reliable fax and modem support was a challenging issue. The technical problem is due to the different clock sources of the Asterisk PC and different Zaptel devices.
Theoretically, all the clocks generate a PCM (voice) packet every 1 millisecond. In reality, because the ...
Session Initiation Protocol (SIP) represents the third wave of Internet usage after SMTP (email) and HTTP (Web). Developed by the Internet Engineering Task Force (IETF), SIP has today become the signaling protocol of choice for establishing realtime communications, including Voice over IP (VoIP) calls. Research suggests that SIP is the VoIP protocol that has replaced H.323 and MGCP and that, for ...
The SIParator is a firewall which can be installed either in the DMZ of an existing firewall, or as a standalone entry point into the LAN. The SIParator's primary function is to resolve the NAT and firewall traversal problem encountered when SIP-based communications are added to the network. The SIParator is designed to first apply strict SIP parser policies to the signaling to verify that the ...
FTS needed to move from a traditional Coral PBX which was shared among many companies in the building (the telephony company provided the PBX services). The customer had no control over the PBX in any aspect and wanted to take advantage of new technology.
The main challenge was to have a seamless transition to the new PBX with minimal downtime. The goal was to install and move to the new phone ...
Many organizations are reluctant to replace their existing PBX because switching to an IP-PBX can be an expensive endeavor. The gradual approach described below provides an excellent conversion strategy with a controlled budget.
Back in the days of wireline telephony, when all phone calls went over the PSTN, businesses would purchase “trunks” – a dedicated line or a bundle of circuits – from their service provider. Today, we have adapted the concept of “trunking” to the IP-enabled landscape resulting in lower telephony costs and rapid return on investment (ROI) plus the opportunity for enhanced communications both within ...
With the evolution of the VoIP market, IP Centrex services and IP-PBX applications have evolved to become two of
the predominant offers for enterprises of all sizes. This market trend is driven by the well known cost-effectiveness
of IP-based solutions which steadily provides a richer set of features and functionalities to end users, whereas
traditional PBX’s and legacy telephony are lagging way ...
Message Waiting Indicator for Analog Lines
A Message Waiting Indicator (MWI) is a light on an analog telephone set that indicates a voice message has been recorded and is waiting for the recipient at that extension.
Since signaling options for analog lines are limited, the PBX uses high voltage pulses over the analog telephone line to activate a small light bulb. In the past, telephone sets ...
