SIP Trunk Feature Guide

SIP (Session Initiation Protocol) Trunk Overview

RingOffice SIP Trunks are a flexible PSTN connectivity solution for businesses. This guide was designed as a quick reference document to assist subscribers of RingOffice SIP Trunks with configuring and using common SIP Trunk features.

While SIP Trunk customers typically have their own feature rich phone system or PBX, there are some features particularly related to fail over behavior which can be managed at the trunk level. This functionality can be managed from the RingOffice Customer Self-Care Portal.

To access the RingOffice Customer Self-Care Portal, use the credentials provided in your RingOffice Welcome Email to login at: https://customer.ringoffice.com

For further questions or assistance with features covered in this guide or with other functionality not covered in this guide, please email helpdesk@ringoffice.com any time.

Failover Forwarding

Each trunk has a powerful forwarding feature that can be managed through the RingOffice Customer Portal. This allows you to set up basic and advanced call forwarding rules. For example, you can have a call ring your trunk but if the call is not answered or if the trunk is down, then forward the call to ring another number or mobile. If the call is still not answered, you can route it to your failover voicemail. You can also preset time of day based forwarding rules.

To manage call Forwarding from the RingOffice Customer Portal,go to ‘IP Centrex’, then Phone Lines. Beside your Phone Line, click the wrench icon ‘Configure’ and then once again go to ‘IP Centrex’ for your Phone Lines. You will see a link on your left called ‘Forwarding’. Here you can set your preferred Call Forwarding rules, Don’t forget to click ‘Save’ after updating your desired settings.
