I am trying to call an mobile phone number from another country. Axon log looks like this. 11:38:04 Call 101 -> sip:0040745xxxxxx@192.168.0.36 11:38:04 Incoming Call from: Carousel on Line: Line 33 11:38:04 Dialing number: 0040745xxxxxx 11:38:05 Incoming SIP call 11:38:17 Call attempt failed - there is no voice or tone signal on the other side 11:38:17 Error returned: 480 Temporarily Unavailable 11:38:17 Call has disconnected 11:38:17 Call 101 -> sip:0040745xxxxxx@192.168.0.36 disconnected Axon waits 13 seconds for the ringing tone signal. Is there a way to configure axon server to wait 20 seconds for the ringing tone signal? The number 0040745xxxxxx rings 1 time after the server disconnects the call. If I try to call local phone numbers everything works fine. Axon version : 2.13 VoIP to Land line device : SHT-4B/USB
