The level of customization of Asterisk is unmatched allowing us to adapt it to the specific needs of our telephony infrastructure; thanks to AGI scripts we extend its functionalities, automating processes and improving operational efficiency. It's remarkable its ability to manage multiple SIP Trunks and operate with more than one provider at a time which gives us stability to optimize costs by choosing the best route for each call.
