I was to recieve a phone call from google drive support , Zoiper answered the voip phone call before the voip phone got a chance to ring.
How do I reprogram so that the voip phone rings first?
The issue that you are experiencing is not caused by Zoiper.
Please note that using the same account on more than one device is not recommended. The incoming calls ring on the device which registered last. Please contact your provider and report the issue.
