It is really difficult having 5550 console on DHCP as at every IP address expiration, it can easily go ff. I wonder if there is a way out of this.
Curiously, rather than the 5550 console keypad receiving its own IP address , is sharing IP address with the PC. The PC is plugged at the back of the keypad.
On the reported false ringer tone, the ringing tone frequently repeats as if calls are incoming into the console but no calls at all. The ringing tone repeats at an interval of 60 seconds. The software version of the 5550 application is 4.2.0.28 while that of the keypad is 9.7.0.3
