When people call from pstn or mobile to our ip phone they hear only one ring and after that it goes to silent . However, we can hear the rings in our ip phone that people are ringing us and we can take the calls. However, if we don't take the call
fairly quickly the people in the pstn may think our system is dead. Can you please let me know what would be the problem?
For more information: We use attendant console, hunt pilot etc.
