I have a client who is using extensively analog lines connected to FXO ports to make PSTN calls.
Whenever they dial any PSTN number, the IP phone starts displaying "connected seconds" even though the service provider is playing ringout or any messages.
This is also causing incorrect billing generated via billing software with CDR generated bills coming to more than 25% of actual PSTN bills.
The customer is using CUCM 6.1.1 with H.323 SRST router with analog lines connected to it.
Please advise if there is a solution to correct this.
