hello everyone im using OpenPhone app to get virtual US number so my assistant can make an outbound call and I can test its performance the assistant itself is using twilio number imported to VAPI it works, however im having latency issues (assistant answers only after 3-4 seconds without any api requests in between) so now im wondering if the reason behind this is me using virtual US number from South Korea (which means that it will be faster when using proper US number located in US) or maybe i messed up with something in assistant settings that i need to look into will be glad if someone can share the experience and difference between testing different numbers form different locations thanks!
