ics7750 fxo phantom ringing

I have an ICS7750 with FXO to a co. The MRP is defined as an h323 gateway and all ports are plared to a 7960 in the office. Having problems with 7960 phone ringing when no one is on the other end of the line. I've tried connection plar opx and that does help. Any suggestions??

Re: ics7750 fxo phantom ringing

A similar problem is discussed in the following bug where there are Calls through MRP from PSTN to IP phone.One of the reason behind it is, when a call is connected and completed, the on-hook status signal doesnot reach the IP Phone and hence, the call rings back.When answered, it will result in dead air. This might be a problem with the ICS7700 as noticed in the bug below.
