What is an advantage of using SIP trunking in Avaya Aura?

The advantage of using SIP trunking in Avaya Aura is its ability to facilitate cost-effective international calls. SIP trunking leverages the internet for voice communications rather than traditional telephone lines, which can significantly lower costs associated with long-distance and international calling. This is particularly beneficial for businesses that frequently engage in global communications, as it results in reduced call charges compared to conventional PSTN calls.

Additionally, SIP trunking supports scalability, allowing organizations to easily add or remove channels based on their needs without significant infrastructure changes. This flexibility enhances the overall communication strategy of a business, further reinforcing the value of using SIP trunking as a part of an Avaya Aura setup.
