Some VOIP services are known to cause turboDial’s Simultaneous Ringing feature to malfunction if one or more of the numbers you configure to be rung are associated with one of these services.
These services immediately signal back to turboDial that a phone call has been answered even though the line is still ringing. This improper signalling causes the other numbers you’ve configured in your turboDial Simultaneous Ringing group to never ring.
The services that have shown this problems are:
- Twilio OpenVBX based systems
You should not configure your turboDial Simultaneous Ringing feature to ring phone numbers associated with these services. And be aware that other VOIP services may have a similar problem. Always test your Simultaneous Ringing configuration to ensure it functions as you intend.
