Vobiz is an Indian telephony provider. Vobiz uses an outbound trunk for the calls Bolna places and an inbound trunk for calls to your numbers, so you create both in Vobiz and connect them to a single trunk in Bolna.
This page connects Vobiz over a SIP trunk. To connect your Vobiz account to Bolna as a telephony provider instead, see Using Vobiz.

​
Before you begin

  • A Vobiz account with balance and at least one Vobiz phone number.

​
Set up Vobiz

1

Create the outbound trunk

In the Vobiz Console, open SIP Trunk → Outbound Trunks and click + Create New Trunk. Enter a Trunk Name. Under Authentication & Linking, add one way for Vobiz to recognise Bolna:
  • Credentials List: create a credential with a username of letters, digits, underscores or hyphens, and a password of 5 to 20 characters with at least one of ~!@#$%^&*()_+. Save both; Vobiz does not show the password again.
  • IP Access Control List: create one with Bolna’s signalling IPs 15.252.21.46 and 13.206.230.198.
Click Create Trunk and copy the trunk’s SIP Domain, for example aabbccdd.sip.vobiz.ai. Use this exact domain, not sip.vobiz.ai.
2

Add Bolna as an origination URI

Open SIP Trunk → Inbound Trunks → Origination URI and click + Add Origination URI:Click Create URI.
3

Create the inbound trunk and link your numbers

Open SIP Trunk → Inbound Trunks and click + Create New Trunk. Enter a Trunk Name, pick the origination URI from the previous step as the Primary URI and click Create Trunk. Open the trunk, click Link Numbers under Linked Numbers and pick your Vobiz numbers.

​
Create the trunk in Bolna

1

Pick Vobiz

In the sidebar, under Deploy, open SIP Trunks and click Create trunk. If your account still has legacy SIP trunks, click Open new SIP trunks first. On the Provider step, pick Vobiz, enter a Trunk name and the number of Channels, and paste the SIP Domain into Gateway we dial. Click Continue.
2

Add Vobiz's IPs and credentials

On the Carrier IPs step, add the addresses Vobiz sends inbound calls from. Vobiz publishes these as its origination sources:
  • 13.233.44.61
  • 3.111.255.163
  • 3.111.128.110
Vobiz notes that this set can grow, so check its page if inbound calls are refused. If you created a credential, enter its Username and Password under Carrier credentials (optional). Click Continue.
3

Add your Vobiz numbers

On the Numbers step, enter each Vobiz number in E.164 format, for example +91XXXXXXXXXX, and click Add. Click Continue, check the summary and click Create trunk.
For every field on these steps, see Connect your carrier.

​
Assign an agent and test

  • Inbound: open the trunk’s Numbers tab and, in the Agent column, pick an agent for your Vobiz number. Then call the number. See Receive inbound calls.
  • Outbound: on the agent’s Calling tab, set Telephony Provider to SIP Trunk. In the agent’s outbound call dialog, pick your Vobiz number as the caller ID, enter the number to call and click Place call. See Make outbound calls.
If a call does not connect, see Troubleshooting.
