Grandstream HT286 - no incoming audio

Post by chrisandmj »

When I dial my ATA phone too slowly I get a "This call is not covered by your tarif plan" message after which my subsequent phone calls screw up for some indeterminant time. The nature of the malfunction is I get no incoming sound after dialing (no ringing or incoming sound even though other end can hear me).

I have resolved this by increasing the "No Key Entry Timeout" in the Grandstream ATA device's configuration from 2 to 5 seconds, but wondering why the phone screws up afterwards (for a time) when this happens. Thx.
