Common issues and solutions when using SIMPLE messaging with voip.ms

Ensure the SIMPLE option for your SIP account is enabled in the app, with composing and disposition notifications turned off. If messages are sent but aren’t received, or you can’t receive messages, contact voip.ms.

Common messaging issues in Acrobits Softphone and Groundwire with voip.ms:

Issue	Solution
The app displays an error when I try to send a message.	Enable the SIMPLE option for your SIP account before you start using messaging: Follow the steps at faq.acrobits.net/enable-messaging-in-acrobits-softphone-and-groundwire to enable the SIMPLE option. Disable the Composing notification and Delivery notifications settings below the SIMPLE option. voip.ms does not support these features, and enabling them can interfere with regular messaging.
The outgoing message appears to go through in the app, but the recipient never receives it.	Contact voip.ms for assistance. This issue indicates that voip.ms accepted the message from the app since no error is displayed, but delivering the message to the recipient is the SIP provider’s responsibility. The app only sends the message to the SIP provider, which must then deliver it.
I can send messages with voip.ms, but I don’t receive any. However, I can see the incoming messages in the voip.ms portal.	Contact voip.ms for assistance. This issue suggests that they are not delivering incoming messages via SIP to the app.
