Voice Notification Module with Twilio as the SIP Gateway

BLUF: I am having issues creating a notification profile to use Twilio as the SIP Gateway.

To clarify, my question is not about the Twilio Module, I can send SMS using Twilio Module. My expected answer is to make Twilio work as the voice notification service for Ignition alarms. I would appreciate any experience shared to have this working.

Here is a bit more description of my progress so far:

I set SIP on Twilio side and I was able to call myself using console and python code on my Ubuntu desktop. Now, I am trying to set a notification profile on ignition gateway to do the same when there is an alarm.

The following is my VOIP Gateway Settings:
Gateway Address: {domainname}.sip.us1.twilio.com
Username/Account: {username}@{domainname}.sip.us1.twilio.com
Password: {Password}

Advanced Settings
Authorization Id: {AuthToken}

The rest remains as default.

The status shows registering for a while, then returns “Request Timeout [408]”

On Twilio dashboard, there is no debug notifications, which means, I believe, it does not make it to the Twilio servers.

Am I on the right path at all?

Can anyone who has successfully made it through help me set this up? Thanks.

Sounds perfect.

I am a little confused about whether ignition can use Twilio directly as the SIP gateway or if it needs something in between as the gateway then this gateway uses Twilio SIP.

I have deleted the Authorization Id in the advanced settings because somewhere in twilio documentation user id/authorization id are used interchangeably, thus I believe it is not supposed to be auth_token. That resulted in the same “Request Timeout [408]” :slight_smile:

If I remember correctly, Twilio provides SIP Trunk capabilities, but it isnt a PBX per say. Have you tried the Kymera Systems Twilio module? It supports bi directional sms and voice.

Thanks for bringing the Kymera twilio module to my attention. Your twilio module looks promising. I will provide more feedback after I try all of its features for a while.


Could you please send me the Twilio SIP configuration screenshots? I would like to configure Twilio SIP as well as voice notification in Ignition 8.1.
