Plain and simple: VoIP (Voice over Internet Protocol) allows voice calls to travel via the internet instead of your more traditional phone lines. Here are the network communication protocols that are used together in VoIP:

SIP: starts, manages, and ends the call.

RTP: carries the actual voice packets.

RTCP: monitors call quality, including delay, loss, and jitter.

UDP: delivers voice data quickly with low latency.

This prototype demo is aware that you are reading “{title}”. It can point you back to the current article, but a production article-aware Fin contract is still follow-up work.

Prototype article-aware answer

Because you already asked about invitations, this prototype demo can add the follow-up: use the role selector before sending each invite to limit access to the teammate responsibilities.

Prototype role-limiting follow-up

This prototype demo suggests starting with your workspace profile, inviting the team members who need access, and then connecting the integrations you use.

Prototype getting-started answer

In this prototype demo, integrations are configured from workspace settings. Choose the integration, connect the account, and review the enabled permissions.

Prototype integrations answer

In this prototype demo, invite teammates from workspace settings, then choose the access each teammate needs before sending the invitation.

Prototype invite-team answer

This prototype demo does not have a scripted answer for that question yet. Try asking how to invite your team or open a source article. No production Fin API was called.
