GSM / VOIP brána s velmi širokými možnostmi použití. Umožňuje volání z VOIP sítě do sítě GSM zdarma, za předpokladu použití legální karty GSM daného operátora.
Pro případ blokace portů internetu ze strany poskytovatele lze toto obejít vyvořením tunelů do internetu, což SW GW přímo v základu umožňuje.
You can now make a call from anywhere in the world via a VoIP network and then terminate the call via a GoIP / WoIP to the local telephone network(PSTN). On the other hand, you can also make a call from the local telephone network to a GoIP / WoIP (the GSM phone number) and then dial another number via a VoIP network to anywhere in the world. In these two cases, a VoIP Serviceprovider is required for one side of the call termination. For two fixed locations, it is possible to setup GoIPs at both ends for call terminations without subscribing to a VoIP Service provider.
GoIP/ WoIPcan also be used to achieve GSM roaming via VoIP. The idea is to route all your incoming GSM calls to a GoIP / WoIP via call forwardor simply insert your SIM card to a GoIP/ WoIP. You can then setup the GoIP/ WoIPto forward all incoming calls to another GSM number in the world via a VoIP service provider. The charge per call from a VoIP service provider is significantly lower than the roaming charge.
For office environment, GoIP/ WoIPoffers a quick way to replace the traditional PSTN lines or T1/E1 lines to your IP PBX. There is no initial installation/reallocation charge and no need to wait for installation. Depending on our usage, you can add or remove lines as per your requirement. You can even configure the system so that everybody calls the same number regardless the number of lines available.
Throughout this manual, GoIP or WoIP is referred as “the device”.
