"When I call my DID number, it is not reaching the destination I expect"... This is a common situation when talking about VoIP services. The proper way to test your DID Number with VoIP.ms is using the echo test application in the customer portal. With this feature you can verify if your number is working properly.


How to test your DID with Sound Quality Test

You can use this tool and follow these steps:


Once your number is routed to the echo test mode, make a call from an external number, preferably a landline. If the number is working properly, you will reach the echo test. After the recording, you can talk and the system will repeat everything you say. This verifies the quality of your line. If this test is successful, we can rule out any issues associated with the DID number itself. If you are unable to reach the DID while it is routed to echo test then please let the support staff know via ticket.

Note: If possible, try to repeat this test from at least 2-3 different times to rule out any issues with the calling party.

Trouble shooting

If you are able to reach the echo test recording while DID is in echo test, then the next possible reason for the unsuccessful calls could be something in your local network, VoIP.ms settings in your customer portal, or the device configuration can be affecting the function of our number. There are some important points we need to check for this.
