Question about GSM GATEWAYS

i use a GSM gateway because my service provider gives me cheaper call rates between &#;friendly&#; numbers using the same provider. so i have an extension that connects to the gateway, waits a second or two, then dials the mobile number.

If you are looking for more details, kindly visit chinaskyline.

it also means i can dial in using a mobile at a cheaper rate than calling a landline.

other places i&#;ve set one up have had either lots of free minutes and it&#;s used as a trunk for landline->mobile calls or free calls between mobiles on the same commercial contract, so it&#;s used for all office->company-mobile calls.

In principle, GoIP can achieve all the functions that an FXO gateway can do with additional values listed below. a) With GSM costs getting lower and lower in many countries, it make more sense to use GSM for call termination rather than traditional PSTN lines. With GSM, there are no expensive charges and long waiting period for installation/reallocation. b) You can change the and service provider by just changing the SIM card. c) Text messaging via GSM SMS is powerful for developing other applications. d) You can build your own network easily. 3.

6. How do I insert a SIM card to GoIP? Before inserting or removing SIM cards, please remove the power to the GoIP in order to prevent damages to the SIM cards. The SIM card insertion method for GoIP is different from that for GoIP-4 / GoIP-8.The diagrams below show both insertion methods. For GoIP, a SIM card is inserted with its cut corner in first and its metal contacts facing down. For GoIP-4/GoIP-8, a SIM card should be inserted with its cut corner in first and its metal contacts facing up. 7. How do I insert or remove a SIM card without powering off the GoIP? When a GoIP with multiple channels are in operation, it is not a good idea to remove its power in order to insert or remove a SIM card since other channels are affected. It is possible to shut down the power to each GSM channel via its built-in webpage. This page, shown below (for GoIP-4), is located under the Tools menu and the navigation link is "Tools -> MODEL CONTROL". Select the desired GSM channel to be shut down and then click [Save]. You are now ready to insert or remove the SIM card in the selected channel. Once completed, you can then remove the check mark at the selected channel and then click [Save]. The power to the GSM channel is then restored and normal operation is then resumed.
