Configuring a Vivo Trunk with 3CX

Provider Requirements

Before you configure your Vivo SIP Trunk with 3CX, you must contact a Vivo representative. They will provide you with all the necessary information you need to configure the Trunk as well as the networking setup to route the incoming/outgoing traffic from/to Vivo.

Step 1: Configuring your SIP Trunk with 3CX

1. Go to the 3CX Web Client and follow the guide on how to configure a SIP trunk.
2. Not compatible with Hosted by 3CX.
3. Enter the main trunk number in the national format (e.g. 9553864893).
4. You can only present numbers associated with your account as Outbound Caller ID.

Step 2: Special Configuration

Go to the “Options” tab, scroll down to the “Advanced” section and for the parameter “Select which IP to use in 'Contact' (SIP) and 'Connection'(SDP) fields” select “Use this IP Address” and enter the IP address provided by Vivo for the PBX.

Step 3: Outbound Rules

When configuring your Outbound Rules make sure all numbers are dialed either in the Local, National or International number formats. 

Local Calls: 8 digits length for fixed numbers, usually calls start with prefix 2,3,4,5 or 6. For  Local Mobile numbers, there are regions that have 9 digits length and usually calls start with prefix 7 or 9, however there are other regions with 8 digits length starting with prefix 6,7,8,9.

National Calls: User needs to dial 0 + Operator's Code (for Vivo is 15) + Number of Destination. National calls could use 13 or 14 digits length.

International Calls: User needs to dial 00 + Operator's Code (for Vivo is 15) + Country Code  + Number of Destination.

Limitations

When using a Vivo Trunk, it’s not possible to implement Call Source Identification. This means on a single 3CX installation only 1 Vivo trunk can exist. Also no other provider can exist on the same installation.
