mobiVoIP shows ‘Connecting to Server’ and does not proceed to “Ready to make calls”. What should I do?
Try disabling “Resolve IP using STUN” option from mobiVoIP preferences to allow mobiVoIP to use local IP settings. If you still continue to face the same problem, consult your network administrator to enable ports 5060-5080 and 16506-16526 for UDP transmission. If this troubleshooting does not help, then it may be possible that your ISP is blocking VoIP data transfer. You can confirm this by running other desktop VoIP clients over the same connection to check if they are able to connect.
