Connect Vonage via SIP Trunking

Integrate your Vonage numbers with UponAI using elastic SIP trunking.

1. Create Elastic SIP Trunking in Vonage

   In the Vonage dashboard, locate the SIP section and select “Something else” for the provider type.

   Follow the Vonage step-by-step SIP trunk setup instructions.

   Configure Termination (outbound):

   • Note the Termination SIP URI, username, and password — you’ll need these when importing to UponAI.

   Configure Origination (inbound):

   • Set the origination SIP URI to: sip.retellai.com
2. Move numbers to your SIP trunk

   Purchase new numbers or link existing Vonage numbers to the SIP trunk you just created.

3. Import numbers to UponAI

   In the UponAI dashboard, import the number by supplying:

   • The Termination SIP URI from Step 1
   • The username and password from Step 1

   You can also import numbers programmatically via the Import Number API.

   Once imported, the number appears in your dashboard. You can bind agents and make or receive calls just like with a UponAI-purchased number.
