# Telephony (/docs/telephony)

> Bring your own phone numbers to OmniDimension. Any SIP-enabled carrier works, with fast-path guides for the most common ones.



OmniDimension speaks **SIP** — the standard protocol every modern carrier
supports. If your provider can hand out SIP trunk credentials, you can
plug it in. The pages below are quick-start guides for the carriers we
see most often, but they are not the limit of what we support.

<Callout type="info" title="Don't see your carrier? You're still covered.">
  SIP trunking is provider-agnostic. Start from the [SIP Trunking
  guide](/docs/telephony/sip) — paste your credentials, and you're live.
  Any SIP carrier works the same way.
