# SIP trunk carrier guides

> Step-by-step guides for connecting Acefone, Airtel, Plivo, Telnyx, Twilio, Vobiz and VoiceLink to Bolna with a SIP trunk, and the dashboard preset to pick for each carrier.

Every carrier connects the same way: create a SIP trunk in Bolna, give your carrier Bolna's values, then add your carrier's IPs, gateways and numbers. [Connect your carrier](https://www.bolna.ai/docs/sip-trunking/connect-carrier.md) walks through that flow for any carrier. The guides below add what is specific to each one: where to find the values in the carrier's console and what to ask its team to set.

| Carrier | Create the trunk with | Indian numbers | Guide |
| - | - | - | - |
| Acefone | **Custom** | Yes | [Connect Acefone](https://www.bolna.ai/docs/sip-trunking/acefone.md) |
| Airtel | **Custom** | Yes | [Connect Airtel](https://www.bolna.ai/docs/sip-trunking/airtel.md) |
| Exotel | **Exotel** preset | Yes | [Connect your carrier](https://www.bolna.ai/docs/sip-trunking/connect-carrier.md) |
| Plivo | **Plivo** preset | Yes, with a Plivo account in its India data region | [Connect Plivo](https://www.bolna.ai/docs/sip-trunking/plivo.md) |
| Telnyx | **Telnyx** preset | | [Connect Telnyx](https://www.bolna.ai/docs/sip-trunking/telnyx.md) |
| Twilio | **Twilio** preset | | [Connect Twilio](https://www.bolna.ai/docs/sip-trunking/twilio.md) |
| Vobiz | **Vobiz** preset | Yes | [Connect Vobiz](https://www.bolna.ai/docs/sip-trunking/vobiz.md) |
| VoiceLink | **Custom** | Yes | [Connect VoiceLink](https://www.bolna.ai/docs/sip-trunking/voicelink.md) |
| Vonage | **Vonage** preset | | [Connect your carrier](https://www.bolna.ai/docs/sip-trunking/connect-carrier.md) |
| Any other SIP carrier | **Custom** | | [Connect your carrier](https://www.bolna.ai/docs/sip-trunking/connect-carrier.md) |

A preset fills in the carrier's gateway, port and transport where they are the same for every account, and shows a checklist of what to set in that carrier's console. **Custom** leaves every field for you to enter.

For Indian numbers, also see [Using SIP trunks in India](https://www.bolna.ai/docs/sip-trunking/overview#using-sip-trunks-in-india) for number format and DLT registration.

Once the trunk is connected, [receive inbound calls](https://www.bolna.ai/docs/sip-trunking/inbound-calls.md) or [make outbound calls](https://www.bolna.ai/docs/sip-trunking/outbound-calls.md) on it.
