viewLinc Enterprise Server supports voice
and/or SMS text messaging via the web service provider, Twilio. With a Twilio account and a
network port set up to access the Internet, viewLinc can send default or custom voice calls
and/or SMS message notifications to your users, in all supported languages. Your viewLinc
users can also acknowledge voice calls and SMS messages received from the web service using
their mobile device and PIN.
| SMS message delivery is also possible using a modem. |
- All voice call/SMS notifications are sent from a single phone number assigned by Twilio.
- Notifications are sent to the phone numbers assigned to your viewLinc users.
- Voice calls or SMS notifications sent to
international numbers require additional permissions (see International Voice Dialing
Geographic Permissions in Twilio documentation).
Contact a Twilio account representative to make sure the voice and/or web services you require are available in your region.
When and how voice or SMS messages are delivered is determined by the alarm notification template assigned to a Location, a device, or to system alarms.
Voice Calling Trees
Multiple users can be called sequentially on a call tree; the order is specified by the corresponding alarm notification template which includes a voice call tree. When a voice notification is triggered by an alarm event, a call initiates and delivers the message to each designated recipient, first to last.
Setup Steps
- Purchase a Vaisala Voice Web Service or Vaisala SMS Web Service feature license (contact www.vaisala.com/contact-us).
- Add the feature license to viewLinc Enterprise Server.
- Sign up for a free trial Twilio account (www.twilio.com) to obtain a phone number and configuration information required to enable the voice calling and/or SMS web service feature in viewLinc. Once you determine your messaging volume needs, simply convert your trial account to a paid subscription.
- Configure voice and/or SMS web services in viewLinc. Contact your IT administrator to ensure your network has an Internet-accessible port available (incoming TCP port 12500).
- Create an alarm notification template which includes one or more voice call or SMS web service notification recipients.
