Hi,
after installing firmware version 07.02.06 on my RUTX09 with a Vodafone OneNumber SIM (same number as the mobile phone SIM), calls to the mobile get a "line busy" signal immediately. This happens if VoLTE is turned "off"; when turned "on", the mobile shows the caller for 1 second, but the line is dropped by the router. Checked 07.02.07 with the same result.
When the router is turned off, this does not happen. I downgraded to version 07.02.05 with VoLTE turned "off", and it works again - I can receive calls on the mobile.
How can I fix this with the newest firmware?
Thanks in advance!
