Twilio Conference vs Call

In Twilio, when creating an outbound Call we don't have ability to add third person later. But we can do it when using a Conference. Calls are a bit cheaper than conferences. So it looks strange, why should anyone bother with creating outbound Calls and not start Conference directly?

To summarize: is there any advantage of using Call vs Conference for "regular" (two person) outbound calls? Besides small cost factor.

For two person is not difference, the difference through the documentation is for big groups of call members. The difference between both is to keep latency down that is the main difference with other services.

Conference Allows for audio conference calls with up to 250 participants. The calls are automatically hosted in the closest of the six geographic regions Twilio currently offers to keep latency down.

For calls with more than 250 participants Twilio’s new “Epic Conference” service can now handle an unlimited number of participants.

But, I concrete: is there any advantage of using Call vs Conference for "regular" (two person) outbound calls? No, is'nt any advantage., the main feature is for big groups.

Advantages to conference for 2 person calls

• Set up recording and dynamic moderator functions. Limit who can speak, and dictate the start and end of the conference.
• Implement specific branding like hold music and multi-lingual text-to-speech greetings. Create easily tailored tracking and analysis of participant information.
• Use any preferred programming language to integrate conferences into existing applications. Embed anything from simple audio bridging to large moderated, multi-user conferences.
• International low-latency: Eliminate frustrating crosstalk and keep traffic local whenever possible for natural, real time dialog.
• If needed you could add additional people
• You can have other people call in to a local or toll-free number instead of you calling them directly
