VoiceLink is an Indian telephony provider. VoiceLink has no carrier preset in Bolna, so you connect it as a Custom SIP trunk.
VoiceLink’s own Bolna AI integration guide shows Bolna’s legacy SIP trunks page. Accounts without legacy trunks see the new SIP Trunks page, so follow the steps below. The VoiceLink documentation portal may not load from outside India.

​
Before you begin

Have these from your VoiceLink account:
  • A VoiceLink account with SIP trunk access and at least one VoiceLink phone number.
  • Your VoiceLink SIP username and password.
  • The IP addresses VoiceLink sends calls from. Ask VoiceLink support for these if they are not in your account.

Open SIP Trunks

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.

Pick Custom

On the Provider step, pick Custom. Enter a Trunk name and the number of Channels. Leave Gateway we dial empty: this field always uses port 5060, and VoiceLink listens on port 3300, so you add the VoiceLink gateway after the trunk is created. Click Continue.

Add VoiceLink's IPs and credentials

On the Carrier IPs step, add each IP address VoiceLink sends calls from. Bolna accepts an inbound call only from these addresses.Under Carrier credentials (optional), enter your VoiceLink SIP Username and Password. Click Continue.

In VoiceLink, open Voice Services → SIP Trunks → Create SIP Trunk. Select the client, enter a Trunk Name and set Status to Active. If Bolna is not in the Bot Provider list, select Custom and enter Bolna’s values:Click Create. If VoiceLink asks for the addresses Bolna calls from, give it Bolna’s signalling IPs 15.252.21.46 and 13.206.230.198. The trunk’s Overview tab in Bolna lists these values under Carrier setup, and the SIP trunk overview lists the media ports.

In VoiceLink, open Call Routing → Create Routing and select your phone number. Set Inbound Call and Outbound Call to SIP Trunk, select the trunk from the previous step, set Status to Active, and click Save.

  • Inbound: open the trunk’s Numbers tab and, in the Agent column, pick an agent for your VoiceLink 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 VoiceLink number as the caller ID, enter the number to call and click Place call. See Make outbound calls.
