Premium Quality Origination & Termination
Powerful MS Teams Trunking Coverage
Outbound Coverage - Local Termination
Outbound Coverage - Local Termination refers to the ability of a SIP trunk to make outgoing calls to local destinations within a specific geographic area, usually within the same country or region. "Local" in this context generally means calls to nearby cities, towns, or the same country.
For example:
- If a business in New York has a SIP trunk with local termination coverage, it can make outgoing calls to numbers within New York City or the surrounding areas, possibly extending to the entire United States, depending on the provider's definition of "local."
Outbound Coverage - International Termination
Outbound Coverage - International Termination refers to the ability of a SIP trunk to make outgoing calls to international destinations, i.e., numbers in different countries around the world. This type of coverage is crucial for businesses that need to communicate globally.
For example:
- A company in London with international termination coverage can place calls to clients, partners, or employees in countries like the United States, Canada, Germany, Japan, etc.
Inbound Coverage - Local & International Origination
Inbound Coverage - Local & International Origination refers to the ability of a SIP trunk to receive incoming calls from both local and international numbers.
- Local Origination means the SIP trunk can receive calls from local numbers within the same country or region.
- International Origination means the SIP trunk can receive calls from numbers in different countries.
For example:
- A business in Tokyo with local and international origination coverage can receive calls from local Japanese customers as well as international clients from countries like the United States, France, Brazil, etc.
