Set up telephony with a third-party SIP provider

Give your AI Employee a working number in a country neither Twilio nor Telnyx covers.

Give your AI Employee a working phone number in a country neither Twilio nor Telnyx covers, by connecting a third-party SIP provider such as Wavix or Zadarma. Once configured, the same SIP credentials carry both voice and SMS.

Before you begin

  • Confirm that neither Twilio nor Telnyx covers your target country. The telephony setup overview walks through the country coverage tool.

  • Choose a provider that meets the compatibility requirements below, then purchase a number from them.

When to use a third-party SIP provider

Reach for a third-party provider only when the country coverage tool shows no support from either primary provider:

  • Twilio unavailable: no Twilio coverage for the target country.

  • Telnyx unavailable: no Telnyx coverage for the target country.

  • Tested alternatives: Wavix and Zadarma are confirmed compatible with Newo.

  • Everything else: other SIP providers may work, but compatibility is not guaranteed.

Verify provider compatibility

Before buying numbers, confirm the provider meets every one of these requirements:

  • Connectivity type: SIP Registration only.

  • Transport protocol: TCP (preferred) or TLS.

  • Standard ports: TCP/UDP 5060, TLS 5061.

  • SIP credentials: username and password.

  • Outbound SIP proxy: an FQDN.

  • SMS support: confirm SMS capability at the time of purchase.

  • Compliance bundle: a compliance bundle or equivalent must be available for the target country.

Important: Newo supports SIP endpoint registration only — not SIP Trunking. Confirm this with your provider before you purchase, because a trunking-only account cannot be connected.

Collect the required SIP credentials

After purchasing a number, gather these five values from your provider. You need all of them to configure the voice connector.

#

Credential

Description

1

Outbound SIP proxy

The SIP server FQDN including port, for example sip.provider.com:5060

2

Transport type

TCP or TLS

3

Port number

Typically 5060 for TCP/UDP, or 5061 for TLS

4

Username / Authentication ID

The SIP account username or authentication ID

5

Password

The SIP account password

With the credentials in hand you have two options: pass all five values to the Newo implementation team and they complete the connector setup for you, or configure it yourself using the steps below. Either way, Newo validates inbound calling as part of agent turn-up.

Configure the voice connector

  1. Open the Builder.

  2. Navigate to Integrations.

  3. Locate newo_voice_connector and click the three-dot menu.

  4. Select Edit Settings.

  5. Set Provider to sip.

  6. Enter your SIP credentials in the remaining fields:

    • SIP caller id: the phone number in E.164 format, for example +380941234567.

    • SIP connection type: TCP or TLS — must match your provider.

    • SIP hostname: the outbound SIP proxy FQDN with port, for example sip.provider.com:5060.

    • SIP username: your SIP account username or authentication ID.

    • SIP password: your SIP account password.

  7. Click Save.

  8. Click Publish All. The connector now shows sip as its provider.

For network configuration, IP whitelisting, and security recommendations, see Connect a SIP provider.

Set the SMS provider attribute

  1. Navigate to Attributes in the Builder.

  2. Search for sms_provider.

  3. Change the value from twilio_messenger to sip.

  4. Click Save.

  5. Click Publish All.

Voice and SMS are now both routed through your SIP provider. No further connector setup is needed — the same credentials handle both channels.

Important: If you set sms_provider to sip before the voice connector is saved and published, the system silently falls back to twilio_messenger. Confirm the connector is published before you test.

Next steps

Telephony is not finished until you have confirmed calls and messages actually flow on the new number.
