What is a Global Title?
A Global Title (GT) is an address of the SCCP protocol for routing signaling messages on numerous telecommunications networks.
Global titles are special addresses that refer to only one destination, but those destinations can differ over a given time frame. It is used to route calls between different networks and to enable services such as number portability.
It is comprised of a combination of digits and letters that are used to route calls between different networks. This address is also used to enable services such as number portability, which allows customers to keep their phone numbers when switching carriers. Global Title also makes it possible for telecommunications companies to provide enhanced services such as call forwarding and caller ID. Additionally, Global Title is used for international roaming, allowing customers to make and receive calls in different countries.
How does it work?
Global Title works by routing calls from one network to another. When a call is placed, the Global Title is used to identify the destination network and the specific location within that network. The call is then routed through the SS7 network to the destination network, and the call is connected.
Global Title can also be used to enable services such as number portability and international roaming. Additionally, various services such as call forwarding and caller ID can be enabled by using the Global Title to identify the destination network and the specific location within that network.
