How does Avaya Aura facilitate international communications?

Avaya Aura facilitates international communications effectively by leveraging SIP trunking and multiple PSTN (Public Switched Telephone Network) gateways. This approach allows for the integration of various communication channels and the ability to manage voice traffic over the internet, which significantly reduces costs associated with international calls.

SIP trunking enables organizations to connect their private branch exchange (PBX) directly to the internet, facilitating voice and multimedia communication without the need for traditional phone lines. By utilizing multiple PSTN gateways, Avaya Aura can ensure redundancy, improve call quality, and provide flexibility in routing calls to different regions around the world.

This combination allows businesses to scale their communication systems according to their needs, making international calls more efficient and cost-effective compared to more limited approaches, such as using only direct dial numbers or restricting calls to local regions. Additionally, the effectiveness of SIP trunking means that special international licenses are not required, streamlining the process of establishing communication across borders.
