last night our RV340 installed the firmware V1.0.03.20 (from 1.0.03.19) with the effect, that incoming VOIP channels stopped working. From looking at the release notes nothing indicates that there have been changes in this area.
Roling back to V1.0.03.19 makes everything work again, rolling forward to V1.0.03.20 breaks VOIP again. So this seems to be a reproducible issue...
Can anybody help or provide more details on what has changed in the firmware?
