Sangoma has introduced an interesting CTI product W400 which adds GSM voice connectivity and SMS capabilities to IP-PBX applications. While CTI applications have been invading many PBX features, this GSM voice as well as SMS facility would add another important feature to CTI applictions which was other wise in exclusive domain of traditional PBX,that is LRU ( Least Cost Routing) using GSM gateway!
Sangoma W400
Normally, most of the GSM operators provide cheaper call rates to its own network. Also, call from landline to Mobile Phone is costlier. So, people have been using GSM Gateway or GSM cards in traditional PBX to route call using the cheapest CO line from PBX extension. For example, if if extension A dials a Airtel Number, the PBX will route the call to go from an Airtel SIM connected to its GSM Gateway or GSM Card. Likewise if extension A dials an international number, it can use a SIM card which has cheapest international call rates. Thanks to Sangoma W400 CTI board, this kind of smart LCR can be implemented in CTI applications too!
In countries other than India where PSTN and VOIP inter-connectivity is not banned, this board also offers opportunity to route calls through VOIP which is a huge savings!
