VOIP GSM Gateways. A VoIP GSM Gateway enables direct routing between IP, digital, analog and GSM networks.

VOIP GSM Gateways

With these devices (fixed cellular terminals) companies can significantly reduce the money they spend on telephony, gp-especially the money they spend on calls from IP to GSM. The core idea behind cost saving with VoIP GSM Gateways is Least Cost Routing (LCR). Through least cost routing the gateways select the most cost-effective telephone connection. They check the number which is dialed as well as rate information which is stored in an internal routing table.

Because several SIM cards and GSM modules are integrated within the VOIP GSM Gateway it is able to make relatively cheaper GSM to GSM calls instead of expensive IP to GSM calls.

Editing from a Linux PC the phone book (contacts list) in an Android phone

Over the years, the phone book on my SIM became cluttered with duplicate entries, inconsistently-named contacts, and so on. I decided recently to tidy up the phone book, and looked for a way to do it from Linux. Now, the last time I tidied up my phone book was back in 2003 when my SIM was in a Sony Ericsson T68i. These days I’m using the same SIM in an Android smartphone: the HTC Desire. Back then I used a shareware application called Mobile Navigator on a laptop running Windows XP. An indirect method of editing a phone book in an Android phone is recommended in many Web forums.
