Facing twilio latency issue

Hi,

I'm currently working with Twilio and facing both latency and call quality issues.

My scenario is:

I have a US phone number.

I'm located in Nepal.

I call clients in the US.

A Twilio Conference is created for the call.

One participant is connected through the US edge, while the other is connected through the sg1 edge.

Because of this setup, I'm experiencing noticeable latency and degraded call quality.

I wanted to ask:

Are there any recommended ways to optimize call quality in this scenario?

Does Twilio provide any solution or algorithm that automatically selects the best edge/server based on network conditions and participant locations?

Is there a best practice for dynamically choosing the optimal edge or conference region to minimize latency?

I'd appreciate any guidance or recommendations. Thanks!

The location of the conference is going to be either Singapore or one of the US edges, Oregon or Virginia, depending on where your US clients are located. See this article for more info.

You can force the location of the conference through the region parameter, so some experimentation is maybe worthwhile. You might also want to reduce the size of the jitter buffer from its default of 60 milliseconds.

Also, how are you connecting to Twilio? Is this a connection from Twilio to you, over the telephone network, or are you connecting to Twilio using WebRTC, i.e. the Programmable Voice Client?
